Can anyone recommend me a sharpening stone for 10" + blades, my current stones are too small to make a complete pass, thanks in advance.
 
On a blade over 10" I hold the stone in my hand and move it along the edge. I've had a time finding a a stone big enough as well. With a steady hand it becomes rather easy to do.

I see those old pictures of the Katana makers using a massive water stone and still have the serious wants for one! :)
 
I use a dmt guided sharpening holder and a 4 inch dmt diamond file. What ya do is to use the holder to hold the file and to keep the knife edge from cutting ya and hone the blade like the old timers used to hone or sharpen briar scythes (...a good scythe blade is at least 16 inches long...) with a whetstone with a handle. Ya may have to work a section of the blade at a time; but it works like a charm. I use it on machetes all the time.

Hope this helps.

My sharpening stones are glued to a belt that runs on a KMG :)

seriously though, the sharpen by moving the stone along the blade method works great, but be careful, easy to cut yourself.

Hahaha, my hands already look like a human pin cushion from work , I just keep Krazy glue close by, I crazy glue all my cuts shut.
 
Industrial grade sharpening rods that fit into a block of wood drilled with 10 20 and 30 degree angles. Epic. Pics soon
 
Gayle Bradley (BladeSports International) and DMT teamed up a couple of years ago to design large bench stones for the big 10" blade competition cutters in hard-to-sharpen steels like CPM M4. I have the DMT 10" Dia-Sharp® Bench Stone which works well for me in 1200 grit. Surface is 10" x 4" with 5 carats of continuous-surface "micronized" monocrystalline diamonds. The stone comes in coarse (325 grit), fine (600) or extra fine (1200) for around $100, which is not cheap but for those who don't want to go the belt grinder route it's compact, easy-to-store, and should never have to be replaced.

Norton stones are available through butcher supply stores in an 11 1/2 X 2 1/2 X 1/2" format. The coarse and the medium stones are Silicon Carbide (Carborundum). The fine stone is Auminum Oxide (Corundum). They are available loose or on a rotating prism in an oil bath.
 
Conan sharpened his sword by holding the stone and running it down the edge. If its good enough for Conan the Barbarian then it must work well. LOL

I've noticed that a lot of older stones are quite large. You might want to check out flea markets, that.. auction site.. etc. etc.
 
Good idea! I've gotten some sweet deals on stones at flea markets and estate sales. One black razor stone comes to mind, that thing cuts so well for an old stone! It leaves a nice satin finish on the edge and a very grippy sharpness.

Be careful not to fall for those dual hones that have one rough side and one "fine" side, you can get the same at Harbor Freight for a buck, and they dont work that well.

As far as running the stone along the edge, yea, please do pay attention, it can come back to bite you very easily. :p
 
My Grandfather did some butcher work on the side years and years ago. He had the largest sharpening stone I have ever seen. Must have been 2 feet long and 18" wide. I wish he could remember what he did with it. Says he still has it somewhere.
