I picked up the two "SEAL" knives at a gunshow yesterday, The "Jungle Machete" and the shorter skeleton style knife. Any thoughts on these Knives? I like both however the sheath on the shorter knife is crap. The plastic rivits are already breaking off. The Machete (despite it's hooky name) seems well thought out, the balance and weight are wonderful. Due to the blade steel (ats-34) and the hardness (57rc) I see it as being more of a large knife than a short machete. Any reviews done on these knives?
