Fallkniven DC4 Diamond Ceramic Whetstone, 7 x 32 x 100 mm

Very good product.

Does a good job. Fair value for money

Contains diamond and ceramic. Quick, easy. Diamond always a bit more pricey but worth the expence.

I use this on Opinel and Swiss Army knives. and it works very well.Pros: very effective and easy to get a razor edge (I’ve had trouble before using a softer water stone)Doesn’t need water.Portable, fits in a pocket.Diamond side cuts quickly, stone side is sharp and hard gets @ good edge.Case is leather and can be used as a sort of strop.Cons: it’s small so might be difficult to use for larger knives? (But ok for my purposes).

Excellent for maintaining blades on the go.

This is an ideal product to carry on you to quickly put a decent edge onto a dull blade while out and about.- It fits easily into a pocket.- The leather sheath has a strop on the reverse.- The diamond side AGGRESSIVELY takes metal off a blade.- The ceramic side is pretty aggressive too!It is, in my opinion, too small (and too course) to use to routinely sharpen your best blades but it will rapidly put a workable edge onto a dull blade out in the field - for that specific purpose this is a 5 star product :-)

This dry whetstone works well. The rough golden side (diamond coated) helps restore dull blades, and the smoother grey side (ceramic compound) helps get a sharp finish.The back side of the leather pouch exposes the fluffy grain, which can be used to wipe off a sharpened blade. Brilliant.

Love these i have the smaller version as well I can get a hair popping edge with them your knife should never be dull if you have on of these
