Every tool has it's use. I have always kept a SAK on me for going on 30 years. There were times I kept a razor knife handy when cutting a lot of cardboard, but otherwise the SAK is all I need. The blade is long enough, but if you need a larger blade, Vic has the 111 and 130 series with locking 3.9"blade plus other basic implements. I'm eyeing the Soldiers knife, AKA the Trekker, with olive drab handle. I can understand different tastes, just don't tell me the SAK can't do everything. If I didn't mind wasting my own stuff, I could've gotten by without a razer knife just fine, but if the company wants to supply the cutting tool, I'll not turn them down.
I doubt that I'd want to baton with any folder, the fact is batoning is a recent development that's seriously overrated and I'd prefer a hatchet for chopping wood. Knife chores can be done with any knife, but sometimes you need to punch leather. The corkscrew is great for undoing knots and who doesn't need a screwdriver occasionally.Can opener and bottle openers are even more handy. If you need to scrape some paint, do you really want to use you're knife edge or a screwdriver. That's the beauty of SAK's. When you only have a blade, sooner or later you'll try to use it as a screwdriver, scraper, prybar or more stuff that a SAK actually has the proper tool for. The only other knife I'd carry is a Leatherman, but for me those are a bit cumbersome for my taste. I'll stick with my SAK, it's all I need.
