I read the field report for the buckmaster and seal use. I thought it got a complete knockback because of these things;
- sawteeth not affective at all
- anchors design use were confusing and a little gimicky
- too heavy
I never knew they were actually ever issued to the seals - interesting!
I use to own one whilst going through the Rambo craze (admit it, didn't we all

), and she was a tuff lil peice, but apart from cosmetic value and collectable interest, I wouldn't use one for trecking, survival or other.
Busse still has my vote. I have not found any better and that includes customs. I think you UK guys can look at the link below for Busse knives, I do not think they have an 'actual' UK supplier (???);
Give Dirk a buzz, very helpful and an alround nice bloke.
