Hi,
Which knives are you speaking of?
As a rule, at least from my experience, Al Mar knives are top notch, especially the ones made in recent years.
The SERE2k is liked by many of the forumites here as being a top notch knife with a good steel.
I've had several models and they've served me well. I currently have a SERE2k and an old ats34 ultralight lockback folder, both of which I plan on keeping.
Good luck,
Thomas Zinn
