A few models that you are able to gripflick cannot be compared to a controlled deployment, and frankly, I'm surprised that no one else has called you on that yet. Grabbing the blade, flicking the knife hard and hoping to open it, then having to re position the knife properly in your hand isn't in the same league as a properly sorted modern design with a flipper, wave feature, thumb-stud, Spyderhole, etc. You aren't the only one who's done that to a Buck 110. I still wouldn't carry that knife over a modern folder.
Like, grabflicking an Opinel? What? That is the most awkward thing ever, and certainly not something I'd want to do if I actually needed a quick or efficient deployment. So, at the end of the day, I am glad that you have a technique that works for you on a few knives. Me, I like having natural control of the knife at all times as soon as it leaves my pocket. Your mileage may vary.
Hmmm.... we aren't communicating well. I'll try to clarify.
First, I'm not suggesting that traditional single blade knives are as easy or fast to deploy as modern OHO designs. There's really no comparison, just as there's no comparison that an automatic transmission is easier to use than a manual transmission. IMO, modern OHO designs make more sense in any of the following situations:
- When you need to quickly deploy a knife like sailing, rafting or kayaking.
- When you need to deploy your knife 100s of times a day like in the trades.
- When the user is relatively new to knives and has weak knife handling skills.
Modern designs are easier to learn and they are faster. No dispute from me on that.
While I noted that a knife like the Buck 110 can be drop opened, I didn't mean to advocate for that. Quite the contrary. I think that is a poor way to open a 110 as it's hard on the knife and, as you correctly note, not well controlled. It's a fun party trick if you go to the same kind of parties I go to, but that's all that it is.
My preferred method of one hand opening a Buck 110, a Case Sodbuster, an Opinel or any other traditional design with a pinchable main blade is very different and very controlled.
1 Pinch the blade with thumb and forefinger.
2 Press the frame down with your middle and ring fingers. The blade is now partially open.
3 Hook the end of the frame on your thigh and open the knife. Done correctly, you will be holding the knife in a choked up hold with your thumb and fore finger pinching the blade and your other fingers holding the frame.
4. Press the butt end of frame on your thigh to safely slide down the knife to a normal grip.
I'm guessing I'm older than you by decades and that the difference between us is that the procedure I've just described was simply accepted as the normal way to one hand open large folding knives. Stunningly, we didn't talk about it on the internet but we did talk about it when fishing and camping and screwing around and everybody I knew who had a knife like the 110 did this.
But, I recognize that talking about is like trying to describe to my kids how to drive a stick. Their eyes glaze over and they shake their head and ask, "Why would you ever drive a car with a manual transmission?"
I try to tell the that after about 6 months, people don't even think about shifting because it becomes so natural and for me, as somebody who grew up with the 110 and knives like it, I don't even think about one hand opening my big traditionals. I just do it, even with gloves on. My kids can't drive sticks and I'm sure there are people on this forum who can't one hand open traditionals easily. In both cases, that's just a matter of lack of practice and experience and in both cases, newer designs are, indeed, easier.
Regarding the Opinel, I hated mine the first year I owned and and I complained about it a lot on the traditional forum. Luckily some guys there helped me out. One guy used to work HVAC and used an Opinel 9 as his work knife. He noted that this same approach worked on Opinels. More importantly, he pointed out that the Opinel, lacking a spring, is safer both one handed opening and just as importing one hand CLOSING. The Opinel is not a fast knife to open but it is the safest to operate one handed of any folding knife I own, very much including my modern ones.
