they're strong knives. the only problem i have ever had with the 119's is if you use them to do a lot of "chopping" on heavy stuff, the blade guard starts coming loose and the layers start getting miss-alligned. see, the guard is actually three layers. the first is aluminum, then a piece of micarta or something similar, and then another piece of aluminum. if you look close you see the layers. ive seen this happen on more than just one knife. this doesnt stop the knife from functioning, just doesnt make it look as pretty as before. i suspect if one kept usuing the knife for a long time as a heavy chopper the guard pieces MIGHT, notice i said might, actually get loose enough to start rattling. but that would take extreme abuse if it ever did happen.,,VWB.
