Recently picked up a couple first gens. The 5 is really MY knife. I think I'll hold onto it for a while. Weird thing is, the 5 makes shavings and curls really well and I didn't see that coming. The 10? Well let's just say I don't chop with knives..... Now I do. Nothing is safe! The only thing I'm not 100% on are the color of the scales. Obviously brown is ok for these users but I'd really like some red linen or even black. The first ten handles are really tough to find and it seems like there aren't a ton of 5's. Btw if anyone wants to get rid of their 5 let me know, I could use a spare.
