Seeing as I use mine primarily for opening boxes, they stack up fine! :-)

Seriously, the blades on all of the sgians we carry are the same. The only difference is the handle and sheath on them. The blades are all stainless Seffield steel.

I'm really not a knife afficianado, so I hesitate to comment on quality, because I don't feel qualified. All I can give is my opinion, that they are as good as any standard commercially available sgians I have seen. These are all made in Scotland -- the blades are not coming from Pakistan or India, or wherever.

The only blades I've seen that have been a noticably higher quality are hand crafted blades, but typically sell for ten times as much....
