Equipment Needed to Start a Knife Sharpening Business
I started with one machine, a set of belts, and some compound. Total cost: under $300. Within two months I was doing $300+ days. Here is the exact gear list, organized by what you need on day one versus what you add as you grow.

Day 1, Must Have
Work Sharp MK.2 + Blade Grinder Attachment
$280
Where to buy: Amazon or WorkSharp directly
The go-to for mobile sharpeners. Fast enough to do a knife in under 90 seconds. Handles everything from chef knives to lawnmower blades. The blade grinder attachment is not optional, it is what makes this system work for business use.
Abrasive Belts, 120, 400, 600 grit + leather strop
~$40
Where to buy: Amazon or WorkSharp directly (Cliff Curry as premium alternative)
Do not buy the cheapest belts you can find. Quality belts cut cleaner, last longer, and leave a better finish. The leather strop belt is essential, it polishes your edge to shaving sharp and removes the micro-burr left by the abrasive belts.
Stropping Compound
$15
Where to buy: Amazon
Applied to the leather strop belt, this compound polishes the edge to a mirror finish. Use a smooth-applying compound, not chalky. A few passes with compound takes a knife from "sharp" to "this slides through paper".
Practice Knives
$20–30
Where to buy: Goodwill or Facebook Marketplace
Never learn on customer blades. Buy a set of beat-up knives from a resale shop and sharpen them until you are confident in your technique before you take your first paying customer.
Month 1, Strong Upgrades
Riser Platform
$60–80
Where to buy: Work Sharp or third-party
The single best upgrade you can make. It raises the sharpening platform to belt level so you hold the blade flat instead of lifting it at an angle. Eliminates the angle inconsistency that beginners struggle with. Magnetic platform keeps the blade locked in position.
Knife Angle Reference Chart
Free
Where to buy: Print and laminate, available online
Every knife brand has a factory edge angle. Wusthof runs 14°, most German knives 15–20°, Japanese knives 10–15°. Having a laminated chart in your kit means you never guess, you look it up and set it correctly.
When You Go Mobile
Portable Power Station
$200–300
Where to buy: Amazon (Jackery, EcoFlow, etc.)
Once you are ready to sharpen away from a wall outlet, pop-up events, farmer's markets, restaurant back doors, a 300Wh station runs your Work Sharp for hours. Start with porch pickups first. Add this when volume demands it.
Month 3+, Volume and Speed
Second Work Sharp MK.2 (Backup)
$280
Where to buy: Amazon
Once sharpening is your income, a machine failure cannot shut you down. A second unit doubles as a demo machine for events or lets you run two setups simultaneously at large pop-ups.
Belt Storage System
$20–40
Where to buy: Hardware store
A small parts organizer keeps your belts sorted by grit, labeled, and protected. Bent or contaminated belts sharpen poorly. This takes five minutes to set up and saves headaches.
BESS Tester (optional)
$80–200
Where to buy: Edge-on-Up
Measures sharpness in BESS units, lower is sharper. A utility razor blade is around 200 BESS. Not required, but it turns sharpness into a number which helps you track your technique improvement over time.
What to Skip
✕
Pull-through sharpeners
They remove too much metal and leave a weak, toothy edge. Not appropriate for professional results.
✕
Basic whetstones for primary business use
Whetstone sharpening takes 10–20 minutes per knife. At $10 per knife, that is $30–60 per hour. Belt grinders do the same knife in 90 seconds.
✕
Electric honing rods
Honing realigns the edge but does not sharpen. Customers often confuse the two. You are a sharpener, not a honer.
✕
Cheap Amazon belts
They wear out fast, leave a rough finish, and cost more per knife sharpened than quality belts.
✕
Overthinking mobility on day one
Start with porch pickups and a wall outlet. You do not need a power station or vehicle setup until your volume demands it. Get customers first, then optimize for mobility.
FAQ
What equipment do I need to start a knife sharpening business?
The minimum is a Work Sharp MK.2 with blade grinder attachment ($280), quality abrasive belts in 120, 400, and 600 grit plus a leather strop, and stropping compound. A riser platform upgrade is highly recommended. Total starter cost is around $355.
Do I need a whetstone to start a sharpening business?
No. Most profitable mobile sharpeners use belt grinders, not whetstones. The Work Sharp MK.2 is faster, more consistent, and handles a wider range of blade types. Whetstones take far longer per knife and are not practical for volume work.
How much does it cost to start a knife sharpening business?
You can start for around $355: Work Sharp MK.2 ($280), belts from Amazon or WorkSharp (~$40), and stropping compound ($15). Practice knives from a resale shop add another $20–30. A riser upgrade adds $60–80 but pays for itself quickly in consistency.
Can I use a cheap knife sharpener to start a business?
No. Pull-through sharpeners and basic whetstones will not produce professional results fast enough to run a business. The Work Sharp MK.2 is the go-to for mobile sharpeners because it is fast, portable, and produces a razor edge consistently.
What belts should I use for knife sharpening?
Start with 120 grit for chip removal and reprofiling, 400 grit to establish your edge and burr, 600 grit to refine, and a leather strop to finish. Buy belts from Amazon or WorkSharp directly, Cliff Curry is a premium alternative with excellent quality.
