I am a big fan of Mike's knives, but i'll say that when i squeeze his liner locks a certain way while gripping, i can feel the liner move to the left a little, whereas with any framelock, Mike's included, generally, any hard gripping or twisting does not cause the lock bar to move to the left, in fact, usually the opposite, so, if the knife is to be a user, I say framelock, for a collector piece, id go with liner locks since as was said, the combination of carbon fiber/G10 and a Ti bolster is more pleasing to the eye. None of Mike's knives i have ever had failed a spine whack test, I have had many well regarded knives fail the same test, and the fact is, i just whack them on the heel of my hand, nothing harsh, and if a lock can't withstand this, i feel its a defective lock, Mike's are all very solid.
For the money, you cannot get a better knife of this type IMO.
A well fitted lock is truly a thing of beauty, unfortunately, they're not all that common... But there aint nuthin wrong with Mike's liner locks, to wit...
