I think my mind is made up. Kershaw has sold me on that AO thumb stud- AWESOME! Looking to go with the Spec Bump with the S30V blade. I am 6"5" and hands run a little larger (just like Offset). I will go to the local shop tomorrow to feel one, but wanted to see if anyone had any feedback. I tried a ton of knives the other day, but that quick opening I just cannot say enough about. Thanks, Offset, for the recommendation. I know I am using the wrong terms, but the Spec Bump can be opened with the thumb stud like the Blur, correct? Are there any others I should look into while I am there (other brands?). I want the good blade metal cause I would like to pass this knife on to the grandkids one day (long way away)- I know it's corny, but I wish I had my grandpa's knife.
