I haven't seen P pinnah start this thread so I thought I would as I think it is an interesting topic, especially for those of us that carry modern knives but might like other options from the traditional realm of knives.

So what is a traditional slip joint knife that can be opened one hand? No thumb stud. What is the technique? I'm curious.

Here's a link to a post in another thread on a different topic. I'd rather not continue to derail that thread, so let's discuss this topic here!

OK I got my GEC to the half stop. I just nearly cut myself 3 times and maybe popped something.

I've seen the vid from collector knives where he just pushes the blade open by pressing the ball of his thumb against the bare edge. I guess I better harden up!

That was a lionsteel with a way softer pull though. I'm gonna try it. If I'm not back in 5 minutes send band-aids.

If I did that with my bull nose there would be blood everywhere. I also don't like the idea of putting that much pressure on the blade/pivot. I'm wondering if there is a different technique I'm not seeing or if only certain knives work.
 
OK I got the Lionsteel Roundhead open with one hand. No EO notch but it has a pretty soft walk and talk.

I pinched it to the half stop and then I must confess I didn't use the ball of my thumb on the blade. I pushed against the kick and opened all the way.
 
I don't have a pinchable slipjoint on me today, but I use the same technique. I can only do it on larger knives with light pulls.

One arm jack is the only one I can think of. Case russlock has a linerlock so I am not sure it counts as a slipjoint.

But I have a feeling he was confusing slipjoints and friction folders.

Was that even a walk? That was crazy soft.

Nailbreaker or nothing for me.

It's a very smooth lockback for sure;)

This large toothpick is just as pinchable one-handed with the same technique, but it's not in my pocket today...so no video:(

OK cut the tip of my thumb with a Beer Scout so I think I am satisfied with today's testing.

Beer Scouts, GEC, a Nortwoods Fremont & Hawhtorn Jacks all can go to the half stop but no further.

A Victorinox SAK (mechanic) is doable if you have a few minutes. Not a harsh pull but not much to grip.

I pinch the blade with thumb and forefinger and use my other fingers to open the knife so it's not being side loaded; a opposed to mimicking the thumb only motion of a modern knife but really forcing your grip into the blade.
 
Here is the technique that I've used for years. It's easy or hard like a stick shift is. Once learned, it becomes second nature. But, just as driving a stick in stop and go traffic annoys some people, this would get old for jobs requiring near constant access to a blade.

Primary feature needed is a main blade that can be pinched.

Most traditional lockbacks can be opened this way. Closing them one handed is more perilous depending on their execution.

1) Hold the knife with the butt end out and pinch the blade.

2) Pinch the blade firmly.

3) Open knife slightly by pushing down with 3rd finger.

4) Hook the butt of the frame on your thigh to open the knife fully.

5) Press butt on your thigh to reposition your hand.

To close the knife...
1) Grasp knife frame with fingers clear of the blade well

2) Press spine against your thigh

3) Close the blade

If you can find it, the Loveless/Lone Wolf City Knife is extremely pinchable and worst case scenario you could always dreamed a small relief notch in the handle/scales.
