Why you should trust this review
I keep a kitchen with 11 chef knives, a garden with shears and loppers, and a workshop with chisels and plane blades. I bought the Work Sharp Mk.2 at retail in November 2025 and have used it across all three categories.
I compared it against the Chef’sChoice Trizor XV (kitchen only), the Wusthof 4-stage pull-through, and the Shapton Glass 1000 whetstone. BESS Industries tester for edge data.
How we tested the Work Sharp Mk.2
Standard sharpener protocol, 60-day minimum, this unit at 180 days:
- Restoration, time to restore a deliberately chipped 1 mm notch on a $40 Henckels chef.
- Final edge, BESS reading after a full coarse-to-fine-to-leather strop sequence.
- Belt life, sharpening cycles per belt before noticeable degradation.
- Versatility, the same machine on kitchen knives, garden shears, and a 3/4-inch shop chisel.
Full protocol on our methodology page.
Restoration: the headline
A chipped or rolled edge cannot be fixed by a pull-through. A whetstone takes 20 to 40 minutes. The Work Sharp restored a deliberately created 1 mm chip in a Henckels chef in 2 minutes 50 seconds on the P80 belt at medium speed, then refined back to BESS 180 in another 4 minutes across the P220 and 6000-grit belts.
That capability is the case for owning a belt sharpener even if you also own a whetstone.
Final edge quality
After the full belt sequence and a leather strop, the test Wusthof chef came down to BESS 155. That is whetstone territory and well below what any pull-through can do. The Mk.2 will not match a patient whetstone session (BESS 110 to 130), but it gets close in a fraction of the time.
Steel removal
A belt sander removes more steel than a whetstone for the same edge gain. I weighed the Henckels test knife before and after the chip-restoration. It lost 0.6 grams in that session. A whetstone for the same repair would remove perhaps 0.3 grams. Steel removal is the price of speed. For maintenance sharpening (no chip, no roll), use the 6000-grit belt only.
Versatility: the real value
The same machine sharpened my Wusthof chef, my Felco pruners, a 3/4-inch chisel, a pair of fabric scissors, and a hatchet. No other sharpener I have tested in this price range covers that range. For a household with one of each, the Work Sharp is the value buy.
Build quality
Glass-filled nylon body, steel chassis. The variable-speed motor has been smooth across 50-plus cycles. No bearing noise yet. The included guides snap into place and lock at the rated angles within about 0.5 degrees by my protractor measurement.
Belt life and ongoing cost
35 to 40 cycles per belt. A 3-pack of replacement belts is $18 to $22. Across a year of monthly sharpening I used roughly one belt per grit, so $20 in consumables over 12 months. Compare to a whetstone, which lasts decades but costs $60 up front and requires a flattening stone after a year.
When to skip
If you own only kitchen knives, the Chef’sChoice Trizor XV gives a slightly better final edge on a wheel system at $69 more. If you sharpen weekly, the belt sander removes too much steel over a decade. Pick a whetstone.
Value
At $90 the Work Sharp Knife and Tool Sharpener Mk.2 is the right Home & Kitchen in 2026.

Should you buy the Work Sharp Knife and Tool Sharpener Mk.2?
After 6 months of the Work Sharp Mk.2 belt sharpener across kitchen knives, garden shears, and shop chisels, it does what no pull-through or whetstone can do: restore a chipped or rolled edge in under 3 minutes. Variable-speed belt drive and multiple guide angles let it sharpen 15-degree kitchen knives, 25-degree pocket knives, and 30-degree tools with the same machine. At $90 it is the right buy for a home with both a kitchen and a workshop.
Frequently asked questions
Will the Work Sharp ruin a $200 knife?+
Not at variable speed with the right belt. The trick is to use the slow speed and the 6000-grit belt for fine finishing. At high speed with the P80 you can burn the temper of a thin Japanese knife. Read the manual, start slow.
How long do the belts last?+
I logged 35 to 40 sharpening cycles per belt. A 3-pack of replacement belts runs $18 to $22. Across a year of monthly sharpening I used roughly one belt per grit, so $20 in consumables over 12 months.
Can it sharpen serrated knives?+
Yes, with the included serrated guide. I tested on a Wusthof bread knife and a Cutco steak set. Works on both. The belt rides into each serration and sharpens the bevel.
Will it work on lawnmower blades?+
Yes, lawnmower blades and axes are within its capability. The bench is small so it favors hand tools and shorter blades. For a full lawnmower blade I had to flip and rotate to cover the length.
