Large knife/Machette sharpening?

[InfantryMyers]

i was just wondering, how do you suggest sharpening a larger knife close to 9 or 10 inches? im used to sharpening around 3-5 inches and im just wondering how the larger ones should be sharpened

I use a belt grinder for sharpening large knives.

+1 for the belt grinder. Then I finish it off on a stone. To off the Burr, then strop.

belt sander or paper wheels with a 1 1/4" wide gritted wheel which makes sharpening longer blades a lot easier. or since you are in the military you can send it to me and i'll sharpen it for free if you pay shipping and insurance both ways. check out my free sharpening thread. http://www.bladeforums.com/forums/showthread.php?t=585019

The few times I've sharpened Machetes, I used a mill bastard file and followed up with a medium grit stone (around 600-1000 grit). Works great if you don't have access to motorized sharpening equipment.

Weird as it is, I use a spyderco sharpmaker as a benchstone for pretty much everything except recurves... It's not hard and is actually pretty convenient, I have all the stones for it from diamond course to super-fine... I can put a good edge on anything with it in minutes

Note: my longest knives are at 10" (blade) and my longest machete is only 14" so I can't say if it would be much harder with a 22" machete or larger

I have used my Edge Pro if I do not have to remove any large amounts of metal due to nicks. If I do I start with the large file and then reset the angle with the EP but this is only because I took my grinder down and stored it for some extra room.

I use a 1x30 belt sander with sharpening belts (or files if doing it manually like on my hay saw/knife) and a coarse/fine DMT Diafold when out in the field.

Another vote for the belt, does it fast, does it right. A convex on a chopper like that doesn't stick as easily, and lasts longer than a V.

I've used a file and a kitchen steel, a puck stone, a belt sander - all steady improvements - but the best results I've gotten are from taking some 3x21" silicon carbide belts and gluing them to a few bases. They wind up around 18" long. 80, 120, 400, 800 grit and some strops the same size. I sharpen them up just like I would any other knife. The powered beltsander works very well too, but my bevels turn out a lot nicer and uniform doing them by hand. Large kitchen knives are very easy to do with this setup.

any recommendations for a puck stone? i think it would be best for my colleagues Kukri which he is asking me to sharpen with a lansky system-hmmm dunno.
cheers.
