I feel you man, I used to hike and bike a lot and nothing irritates me more than people who don't want to share the trail/river and/or don't respect it and are just there to destroy a good thing. I'm really into knives and have been known to break out the sharpening kit for hours on end. I enjoy the entire process of putting a good edge to a blade and especially rescuing an older knife that would've otherwise been relegated to the garbage bin. But I do have a thing for AKs, I will definitely have to check out the scratch build. :P
