What a absolutely wonderful piece of work this piece from Kizer is . The Yorkie in Red Micarta with a m390 blade has a silky smooth action, the fit and finish is absolutely stunning! I have been all over mine like a mother with a new baby, there’s nothing i can find on this model to actually be able to say doesn’t work or function flawlessly. The grind of the blade is bang on with the apex of the edge a perfectly ground Asymmetrical grind one of of the sharpest factor edges i have yet to come across, and i have at least 150 in my growing collection of knives. The Yorkie is a stunning yet simple stud opening action knife, that you would be kick yourself if you missed out on, i will honestly be recommending this piece to a lot of my friends that are all so knife collecting people as it is definitely one not too miss out on.. AAA+
