Great question xbxb, I struggle with this one myself. I may be an odd ball or psycho of this great forum but I carry at all times a Schrade LB8, a Schrade ST1 Multi Tool, Schrade 194OT that I interchange from time to time with a Schrade stockman Texas Ranger or the Schrade Trapper Texas Ranger, I also carry a Spyderco Police model. I have on my keychain a small Leatherman multi tool scissors for cutting my cigars along with Schrade Simon SS1 on my truck key chain. Now with regards to the Leatherman, I would replace it with the Schrade ST2 Tough Chip if I could ever keep one. I have bought 11 ST2s only to have them taken away from me by family members, I will buy a few more so I could keep one. I use just about each and every one of these tools at least once a week, with family members asking to borrow one once and a while as well.
Most people only need one pocket or sheath knife; many don’t carry any at all. I think our society today has made anyone who carries tools like these an outcast. Airports cease them, employers regard them as weapons, and schools have banned them, we as a society have gone nuts and have lost it. I remember my father telling me that he was in the rifle club at his high school, this class was supported by an NRA instructor. The only problem he said at the time was a city bus driver told him that he better have his rifle in a scabbard next time he boards the bus, look at how far Left we have gone. I for one feel stripped if I don’t have a knife on me and anyone I feel who has ever carried a knife and looses it feels a great lose. As for your question, the knife that fits your needs is the one you should carry. Also keep in mind to have a replacement knife, just in case something happens to your carry knife. Thanks for the question, maybe some of the other collectors here on this great forum can straighten me out as well.
