I posted a question for you at the end of my "twich xl who likes em" post. I just wanted to make sure you saw it so I created another post to ask the same question. Could you give me your opinion of the Twich XL? Does the blade assist spring hold up well a.k.a. any problems with breakage? How much do they cost if one breaks. I carry this knife very often and just like the add says "The action is addictive". Am I causing any unknown problems by flipping it open alot? One poster complained about the skinny blade stop pin. Have there been any problems with it breaking? Thanks in advanced.
