I've owned khukuries for a couple of years. However, my ability to sharpen one or any other knife is "less than optimal". I can sharpen a knife enough to hack my way through a block of aged cheddar cheese (not that soft medium stuff), but when it comes to slicing well my performance isn't great. Some forumites in the past tried to help my thickheadedness but sadly failed. This was in the age before youtube so people could only describe in words. Yvsa had some good tips, and Pendentive made a CD with some videos while Uncle Bill laughed and offered to sell me more khukuries. Others offered bits and pieces of information but I either never got the hang of them or figured them out. I left the knifie world for a while but some tomahawkery lured me back to it. There's not much on youtube but a couple of channels that have some good information. So.. how do you sharpen your khukuries? Teach a thickheaded person like myself to sharpen. I have a nice Bura BAS that I think had a couple of Nepali termites in the sheath. The wood in the sheath turned into sawdust and I have a dull BAS with no sheath that has sat dull for a bunch of years.
