Innovative handheld sharpening apparatus.
Use of diamond and silicon oxide abrasives at 3300 to 2500 grit respectively on flexible backing material create visually observable mirror polished surfaces and refined edges of improved cutting durability with finely sharpened apex compared to hard surface 5000 grit wet stones and 8000 grit diamond stones.
In very little time without much skill anyone can create these polished mirror shine convex and straight edge shapes that are super sharp with an ALLHone edge honer.
The ALLHone honer fitted with diamond, silicon oxide polyester film or a ribbon of silicon carbide, aluminum oxide sand paper from your local store both sharpens and replicates the finishing hone of traditional leather strops.
A great combination 800 to 1000 on the frequent change side and 2500 and finer on the opposing side. The coarse side gives the edge micro teeth and after a little stropping on the fine side you will produce an ultra sharp shaving and cutting edge. Recommend 18 degrees angle.
Diamond abrasives on film produces a more polished surface compared to a hard diamond stone due diamonds are more deeply embedded into the film surface for durability than the electroplated diamonds onto a hard surface. So the film surface is less abrasive and polishes.
Silicon carbide breaks down from a pyramid shape into a smaller pyramid so its is practically preferable to use 2500 grit for polishing due to after initial use removing metal it’s points break off producing a smaller pyramid, thereafter a finer grit for polishing. Aluminum oxide polishes well and breaks down slower than silicon carbide but is not as fast at removing metal material initially when the silicon carbide pyramid has not yet broken from use.
Up to 5000 grit produce a very sharp edge. Beyond 5000 grits are not really very practical. An edge is only as fine as the fineness of the grit so using a finer grit will produce a sharper edge but there is also diminished return in the form of less metal removed for sharpening speed time. So for practical field use the 2500 silicon carbide, aluminum oxide and 3300 diamond works well.
