FS-12 or FS-15 metal foot file: matching holder and 180-grit replacement sheets
- 14 min reading time
The Profi FS-12 metal foot file should be paired with the self-adhesive FS-12 replacement sheets, 180 grit, pack of 10. The Profi FS-15 has a separately specified FS-15 sheet pack, also 180 grit and 10 pieces. These manual stainless-steel tools have a similar purpose, but they are different product models with separate replacement references. The number 180 describes the abrasive grade; it does not tell you whether a sheet fits the metal surface underneath. Check the model printed on the holder first, the model printed on the refill second, and only then the abrasive grade.
This guide explains how to select and reorder a manual metal holder and adhesive abrasive sheets. It is not a method for treating painful corns, cracked heels, wounds or high-risk feet. The manufacturer describes both FS-12 and FS-15 as double-sided stainless-steel manual graters with replaceable abrasive surfaces. Its statement that the graters may be used in dry and wet conditions is about the tool's intended use; it must not be interpreted as permission to reuse a contaminated sheet or as a substitute for an instrument-cleaning protocol.
The purchase pairing in brief: FS-12 holder, SKU 131016, goes with sheets SKU 131018; FS-15 holder, SKU 131027, goes with sheets SKU 131028. Both named refill packs contain ten self-adhesive 180-grit sheets. The matching model reference is decisive even though the grit and pack count are the same.
1. Are you purchasing a metal tool or an abrasive refill?
FS-12 and FS-15 identify hand-held metal foot files with a grip and two working sides. A ten-piece pack of adhesive sheets is a different article: it does not include another stainless-steel file. Purchasing records should make that distinction explicit. The phrase '180 grit foot file' can be misunderstood as either a complete instrument or a consumable abrasive. Record the model and SKU when purchasing the holder, and the intended holder model, grit, quantity and refill SKU when purchasing the sheets.
The primary manufacturer cards list stainless steel, a double-sided design, changeable abrasive surfaces and dry or wet use for both instruments. These are published product attributes, not independent test results concerning skin outcomes, durability, working time or the suitability of every disinfection method. Read the FS-12 manufacturer specification and the FS-15 manufacturer specification if you need to check the construction. The division between durable metal tool and replaceable contact surface matters particularly when a salon is restocking: a pack of paper inserts will not replace a missing handle.
Different shop languages also introduce different general names for the same class of equipment: metal grater, foot file, rasp, lime à pieds, pilnik or Fußfeile. Such translations are less dependable identifiers than FS-12, FS-15 and their exact item numbers. A clear purchase order might say 'FS-12 / 131018 / 180 grit / ten sheets' rather than repeating a shortened translated title. That simple convention makes it easier to check an invoice, warehouse label or supplier reply without confusing the two models.
2. FS-12 versus FS-15: which differences can be verified?
The original information identifies both as double-sided stainless-steel instruments with replaceable abrasive faces. It identifies FS-12 as article 131016, EAN 5906717430701 and FS-15 as article 131027, EAN 5906717430817. Those numbers show conclusively that the holders are distinct catalogue products. They do not demonstrate that one has a better grip, removes callus faster, weighs less in the hand in a meaningful way or accepts the other model's paper. Comparative independent performance data for those conclusions was not found.
In an adhesive-sheet system, the metal working surface provides the base to which the consumable layer attaches. A refill needs to be intended for that precise base. 'Double-sided metal foot file' is therefore not enough information for choosing replacement stock. Prohaar lists the FS-12 metal foot file and the FS-15 metal foot file as separate current products. If both versions are present in a studio, keep that model distinction on the equipment register, purchasing template and refill storage label.
The verified manufacturer entries do not provide a complete, independently confirmed drawing of the adhesive areas with dimensions and fit tolerances. For that reason this guide does not invent widths or lengths, suggest cutting an FS-12 sheet to fit FS-15, or infer compatibility from the shape visible in a product photograph. If the marking on an existing holder has worn away, identify it through the initial order, original packaging or SKU history rather than guessing from its outline.
3. Correct 180-grit refill references: 131018 and 131028
For FS-12, the matching product is the FS-12 self-adhesive 180-grit replacement sheets, SKU 131018, in a pack of ten. For FS-15, choose the separately listed FS-15 self-adhesive 180-grit replacement sheets, SKU 131028, also in a pack of ten. These labels refer to the sheets rather than to additional metal handles. They represent two deliberately separate holder–consumable pairings, even if the abrasive grade and number of pieces appear identical on the boxes.
The refill model references remain decisive: 131018 for FS-12 and 131028 for FS-15. The manufacturer page for item 131028 confirms EAN 5906717430824. A barcode helps identify an item but does not prove identical adhesive areas or interchangeability. Check the identification on the delivered packaging as well.
The English manufacturer page for item 131028 says FS-15 in its title but FS-12 in its descriptive sentence. This is a source contradiction, not evidence that one sheet fits both holders. The title and item code identify the FS-15 refill; if in doubt, ask for confirmation of the correct pairing before ordering.
4. Why 180 grit is not a measurement of fit
Grit 180 identifies the abrasive classification of the replaceable sheet. It is not a measurement of length, width or the adhesive contact area. Both refill articles use the same nominal abrasive grade while carrying different model designations and product codes. This distinction is central to a sensible purchase: the grade tells you about the abrasive surface, whereas the model tells you which holder the refill was made for. One property does not establish the other, just as a common consumable material does not guarantee attachment to every possible handle.
The current shop cards position the 180-grit sheets for more refined finishing in a professional foot-care setting. Treat this as a description of intended product positioning, not a promise of a pain-free procedure, guaranteed smoothness or universal use on any kind of skin. Nor does it mandate a fixed routine starting with a coarser abrasive. Whether mechanical filing is appropriate at all depends on the condition of the skin and the competence and remit of the practitioner. This article does not convert a product grade into a treatment algorithm.
A box marked simply 'foot sheets 180' is ambiguous when a workshop uses both FS-12 and FS-15. A more reliable label is FS-12 · 131018 · 180 · 10 sheets or FS-15 · 131028 · 180 · 10 sheets. When the model appears first, somebody preparing a workstation is less likely to retrieve the right abrasive grade in the wrong shape. Model-led stock organisation protects the accuracy of purchasing decisions without claims about unmeasured tool performance.
5. What can the double-sided construction tell you?
The manufacturer's double-sided description concerns the metal holder, which offers two working sides on which the abrasive surface can be replaced. It does not mean that one refill pack contains two different abrasive grades. Neither does a ten-sheet pack mean that ten fully equipped double-sided foot files are supplied. That would confuse loose consumables with complete instruments. The catalogue confirms the number of individual sheets per refill pack; it does not prescribe an exact number of procedures or a predetermined rate of consumption for each side.
The holder and sheet have different functions. The stainless-steel component provides a support and grip, while the adhesive abrasive is the replaceable contact layer. Keeping those roles separate helps with purchase orders, workstation organisation and used-material handling. It does not establish a guaranteed tool lifetime, a specific number of safe treatment cycles or an all-purpose method of cleaning the holder for a new person. Such conclusions require model-specific instructions and applicable hygiene standards, not an assumption based on the metal alone.
6. A purchasing checklist that keeps the two systems separate
Use four fields for the purchasing line: holder model, holder SKU, refill SKU, and refill grade plus quantity. The accepted pairings are FS-12 131016 → 131018 and FS-15 131027 → 131028. This is a product-identification check, not a step-by-step guide to filing skin. The point is to keep the person placing the order from substituting an unrelated pack because both product names contain '180 grit'. Matching the model on both sides of the pair is the primary requirement.
Where several professionals share materials, consider separate labelled containers for the complete hand-held files and for the two refill types. Put the model code before the grit figure on each label. On arrival, compare the supplied SKU with the purchase order before the packages enter shared stock. This is a straightforward receiving check: no unverifiable promise of how long a sheet lasts is needed to make it effective at preventing incorrect replenishment.
7. Wet or dry use is not a cleaning specification
The supplier describes both manual files as suitable for dry and wet use. That describes potential working conditions for the metal grater. It does not establish that an adhesive consumable can be wetted repeatedly, stripped off and reapplied or used again after it has contacted somebody's skin. It also does not state that plain water achieves the cleaning and disinfection standards of a professional environment. The product and the hygiene procedure are separate subjects.
Before a professional use, the state of the metal support, abrasive and attachment should be checked. A visibly damaged, loose or contaminated sheet is not appropriate as a prepared contact surface. Used contact material must be handled under the practice's suitable arrangements instead of being put back with unused refills. Care of the reusable component depends on applicable rules and the manufacturer's actual instructions. The checked listings do not establish a disinfectant concentration, exposure time, cycle temperature or verified sterilisation route, so this article deliberately supplies none.
Stainless steel should not be confused with zero maintenance or universal resistance to every chemical. In the same way, 'wet use' does not guarantee that the adhesive retains its characteristics after repeated washing. A studio that needs instrument-reprocessing details should obtain instructions for the precise model; a general online description of construction materials cannot stand in for a validated procedure. This is a critical distinction when moving from an ordinary product selection to professional infection control.
8. Skin risk comes before the choice of abrasive
This purchase guide is about equipment for ordinary professional cosmetic work on intact skin. It is not a recommendation to file high-risk feet. People with diabetes, circulation problems, reduced sensation, impaired immunity or older people may face more serious consequences from skin damage. The NHS guidance on corns and calluses advises those at higher risk not to treat corns and calluses themselves, and to seek a GP or foot specialist instead. Bleeding, discharge, wounds or severe pain are further reasons for a medical assessment before considering cosmetic filing.
A finer label such as 180 grit does not remove those risks. A fresh sheet cannot make neuropathic skin, a previously ulcerated foot or a wound appropriate for a routine salon service. Neither of the primary manufacturer pages supplies clinical evidence that FS-12 or FS-15 treats a high-risk foot painlessly or prevents injury. This article therefore includes no technique for removing deep callus, treating corns or managing foot wounds. These matters belong to qualified medical professionals using their own current clinical guidance.
For any studio, the decision should proceed in the correct order: first determine whether a cosmetic procedure is appropriate and within the practitioner's qualifications, then consider the equipment. Where symptoms call for podiatry or medical care, no metal file model or grit value takes priority over that assessment. A trustworthy buying guide should distinguish item matching from diagnosis and avoid language that implies a guaranteed result merely because the product is sold for professional use.
9. Reference summary and final selection
The four records below are identification data, not a comparison of filing speed, pressure, clinical effect or tool life. They are grounded in the present Prohaar listing and the original manufacturer descriptions of the metal instruments.
- FS-12 metal holder: SKU 131016; EAN 5906717430701; double-sided manual stainless-steel file; dry/wet use specified by the manufacturer.
- FS-12 refills: SKU 131018; ten self-adhesive 180-grit sheets labelled for FS-12.
- FS-15 metal holder: SKU 131027; EAN 5906717430817; double-sided manual stainless-steel file; dry/wet use specified by the manufacturer.
- FS-15 refills: SKU 131028; EAN 5906717430824; ten self-adhesive 180-grit sheets labelled for FS-15.
If you already own a correctly identified FS-12, buy the matching FS-12 sheets; if you own FS-15, buy its specific FS-15 sheets. You do not need both holders simply because both listed refills are 180 grit. Keep packs separate if both tools are in service. If the model is unreadable, a delivered item differs from the listing, or a manufacturer's product revision seems possible, confirm the current SKU and EAN with the supplier before choosing a replacement.
Frequently asked questions
Do FS-12 replacement sheets fit FS-15 as well?
Cross-model fitting has not been confirmed by the checked primary information. Distinct model-linked products are offered: code 131018 for FS-12 and 131028 for FS-15. Do not infer compatibility from grit or product photographs.
Is the 180-grit figure the sheet size?
No. Grit identifies the nominal abrasive grade, not the length, width or adhesive outline. Check the model and exact product number to identify the right refill.
Does one refill pack contain ten metal foot files?
No. Codes 131018 and 131028 refer to packs of ten loose adhesive abrasive sheets. The stainless-steel FS-12 or FS-15 holder is sold as a distinct article.
Can these metal files be used dry and wet?
Yes, that is how the manufacturer describes the two graters. It is not a statement that a used disposable sheet may be reused or that rinsing constitutes a verified disinfecting procedure.
Does double-sided mean every sheet has two grit grades?
No. Double-sided refers to the metal holder. Both packs in this comparison are identified as 180 grit and no mixed-grade sheet has been established.
Why does an FS-15 refill description sometimes mention FS-12?
Some abbreviated translations contain a contradictory model reference. The title, item number 131028 and manufacturer's product grouping identify the FS-15 refill. The wording mistake does not establish interchangeable parts.
Is a 180-grit file automatically safe for someone with diabetes?
No. Grit alone says nothing about suitability in a high-risk foot. NHS guidance advises people with diabetes, circulation problems, weakened immunity and older people not to treat corns and calluses themselves, but to seek medical or foot-specialist advice.
Buying decision: pair Profi FS-12 with FS-12 180-grit sheets or Profi FS-15 with FS-15 180-grit sheets, and verify the item numbers before purchase. Prohaar editorial team · Product and source review: 14 October 2026.
