Work Sharp Benchstone Knife Sharpener vs SHARPAL 191H Knife & Scissors Sharpener

Buy the Work Sharp Benchstone if you want a sharpener that will last and can put a genuinely keen edge on pocket, outdoor and kitchen knives. It uses diamond plates and a ceramic stone with locked 20° or 25° guides, and owners rate it highly for being simple and fast. The SHARPAL 191H is a small pull-through sharpener that sets a fixed angle with carbide and ceramic slots and holds to the counter with a suction base. It is quicker for a dull kitchen knife or scissors, but it removes more steel and cannot match the Benchstone's edge quality or long-term durability.

  • Choose the Work Sharp Benchstone if you want a guided diamond-and-ceramic sharpener that gives a lasting, keen edge on pocket, outdoor and kitchen knives.
  • Choose the SHARPAL 191H if you want a compact pull-through sharpener for quick touch-ups on kitchen knives and scissors, with a suction base for one-handed use.

What reviewers say

Work Sharp Benchstone Knife Sharpener

  • 4.8 / 5136 ratings

Rated 4.8 out of 5 from 136 ratings, buyers call it simple and quick, with knives coming out very sharp in minimal time. The main complaint is a wish for more replacement diamond grit options.

What people mention
  • Ease of usePraisedBuyers say the angle guides make it beginner-friendly and remove confusion.
  • Sharpening speedPraisedOwners report sharp edges in minimal time, faster than traditional stones.
  • MaintenancePraisedUsers like that the diamond plates need no flattening or reshaping.
  • Grit optionsCriticisedSome buyers want replacement diamond stones in finer grits like 800 to 2000.

SHARPAL 191H Knife & Scissors Sharpener

  • 4.3 / 5247 ratings

Owners rate it well as a fast, simple sharpener for everyday kitchen knives and scissors. The common complaint is that the carbide stage is aggressive and can chew up softer or expensive blades.

What people mention
  • Sharpening speedPraisedOwners say a few pulls bring a dull knife back to cutting again.
  • Steel removalCriticisedReviewers warn the carbide stage grinds away a lot of metal, which shortens blade life.
  • Suction baseMixedIt grips well on smooth counters but can slip on textured or damp surfaces.
  • ScissorsPraised

Questions and answers

Which is better for kitchen knives?
The SHARPAL 191H is quicker for a dull chef's knife, but the Work Sharp Benchstone gives a keener, longer-lasting edge. Use the 191H for fast touch-ups and the Benchstone when you want a real edge.
Which lasts longer?
The Work Sharp Benchstone lasts longer because its diamond plates and ceramic stone are replaceable. The SHARPAL 191H's carbide and ceramic slots wear out and cannot be replaced.
Can the SHARPAL sharpen serrated knives?
Yes. Use only stage 2, the ceramic slot, on serrated blades. The carbide stage would round off the serrations.
Is the Work Sharp good for beginners?
Yes. The 20° and 25° guides lock in the angle, so you do not need freehand skill. Owners call it simple and fast.
Is the SHARPAL worth stepping up to from the Work Sharp?
No, it is a step down in edge quality and durability. Step up to the Benchstone if you want a better edge; choose the 191H only for convenience and scissors.
Which is better for travel?
The SHARPAL 191H. It is pocket-sized and needs no flat bench. The Benchstone is compact but wants a stable surface.
