The hole does make the knife weaker, but for most purposes, you wouldn't notice. Heck, most of the knife use I do doesn't even need a lock. (Considering a UKPK, and debating over whether to go DP or leaf...but that's a different story ) I guess it all comes down to intended use. Does the hole in the Mili's blade make it a lousy knife for slicing and carving and outdoor work? That hasn't been my experience-mine has served me really well.
Does it make it a lousy fridge-stabber or crow bar? It very well might. The Mili is an utterly terrible crowbar, especially for the price.
Does it make it a worse last-ditch knife than if it didn't have the hole? Now that, is debatable. I find the hole more reliable than thumb-studs, especially when cold. (At minus-four degrees Celsius out, the hole is better than the thumb stud. For me. ) Depends on whether your last-ditch use is cutting through a seat belt or a windscreen.
In the meantime, though, it sure wouldn't hurt to get both a Spyderco slicer and a ZT tank
Oh, and on BM discontinuing stuff, don't get me started. I'm worried that if I don't get a Rift real soon, they'll DC that, just 'cause. I want an AFCK too.
J. Mattson, sure was a nice thing for you to do. Hope your 741 gets a good home and is well-loved (used)
