Phil & TripleF....Thanks
Phil, I wasn't for sure about the steel .. so I went to their site and got this info...
154 CM stainless steel blade, Tribocote R40 finish and 6061-T6 Aluminum handle .55" handle thickness. Outside button to release blade. Secondary safety lock.
Doesn't really say what type is used for this particular knife..

.....just stainless.
