Been using this knife at work the past couple days, and the thing had stayed sharp as hell, yet to have had to switch the blade.
Thinking about getting another one to throw in the hunting pack. Box of new blades takes up next to no space, each blade has two sides, takes about 3 seconds to switch blades. And if it hold up as well on animals as it does on copper cable should keep and edge pretty good to.
Maybe a little less flimsy then the skalpal knives? Never used one
paid 15$
Also the one I have has a different locking device for switching blades( a little wheel switch on top the blade holder) and has a locking mechanism for hold the blade in 3-4 different angles can't remember.
