I really debated getting the axe puck, but decided to stick with the field stone. I do have the American mutt puck, which is a pretty aggressive stone once you start really pushing with it. It's almost too fast for soft machetes as it can be tricky to get a finished, usable edge. It's so quick at taking dents and nicks out though, that I still like it. I'm still working out some of the take-along sharpening systems. I think I may just end up with a full-size strop eventually. It takes up more room but it's a lot lighter than a stone. I suppose you could slap some sand paper on it to use as a sharpening surface too.
And thank you for the comments on the designs. I'm really aiming at something a little different than what's available but far from looking like a Klingon weapon.
After the first batch of each knife is run in January/February, I will be announcing something that I think will entice people that are in your situation. Interested but not sure if they want to buy it. It may not lead to a sale but it should let you know if it's for you or not. John and I are going to be partnering on that service as well, with me facilitating all of it. I really think it's going to add value to our little piece of the knife world and allow our customers a more in depth experience with the knives before purchase.
