Norton Crystolon Utility File Sharpening Stone with Wooden Handle, Premium Silicon Carbide, 14'' Overall Length, Grit Coarse

First - get some pipe insulation and make a sleeve for it. Doesn't take long to rough up, sharpens to a working edge in a few strokes, will bring flat knives back from the dead. Never found better, seem them wear completely through (shatter immediately if no sleeve, its just one of those tgings). Size is perfect and it lasts plenty long.

My old one wore out after years of use. So glad I found it again. Sharpens great and ergonomically useful and good size. One thing would improve its safety and that’s to have the handle a little outside the stone so it would protect the hand better. So much better and easier to use than a flat stone sharpener and sharpens better than a steel rod.

I have the 8" bench stone and always find myself standing it up while lapping rough glass so when I found this file I was thrilled. The handle is hefty and matches the weight of the stone. The coarse grit glides through material quickly and evenly. I bought a second file for back up.

Did the job!

Haven’t even used this handle stone but some people actually thought this would work for lawn mover blades and gave it one star...it’s main use is intended to sharpen mechanical insulation knives such as 6” filet knives and binning knives. Not great fir serrated blades but if will. Just sharpen the non serrated edge until it gets a nice edge and then pass over the serrated site one time to smooth out the coarse edge left behind. This stone will typically leave your blade coarse and will result in an excellent edge needed to provide easy slicing into rigid fiberglass pipe covering and foil scrim jacketed non rigid wrap insulation.
