Thanks! Having the sheath open on the bottom is a great idea. Buzz Wilsons work looks great. I do some leather work, and will eventually make my own sheath. I have some good tooling leather just waiting for a project. I have noticed the nylon sheaths collect a good amount of dirt in them. I try to wipe off the blade before re-inserting, but you can't get it all off. I also may try to spray the blade with a little silicone spray, to see if it helps it stays cleaner in the field. Wet soil really clings to the blade.
The more I use it, the more I am liking the Lesche. It really cuts nicely, even with the rocks in the soil. I will get one of the motorcycle grips for it, I think the softer rubber would be much more comfortable and non-slip.
I appreciate the advice!
