Lovin' it. Can't wait to hear about edge retention and sharpening with that O-1. That should definitely be long lasting blade.
When I was out in the bush with Anton, he was using one exactly like this every day. Hard-use, too...not just wittlin' sticks. He cut hard acacia branches, processed firewood, sparked firesteels, other tasks....the edge remained good to go. Sharpening this knife for me will only require some stropping with black and/or green compound on a leather strop block, and occasional touch ups with fine grit sandpaper. I've got a little field kit from Knives Ship Free.com that has everything I need to maintain it. I already stropped it a bit....it is slicing through paper with ease and popping hairs off my arm.
