Now, do you want to have levels of fun with a knife as a play toy that will not only end up putting the pleasure of fidgeting with a well tuned compression lock knife to shame, but also gives you something completely outside the capabilities of the PM2 in any steel?
One that ends up being fun at parties?
Just hear me out on this: you want a trainer knife.
And there's three ways you can go, fixed, folding, and Balisong.
Fixed: BM SOCP Dagger Trainer
Just get it and start playing with it, you'll get what I'm talking about. You'll be doing spins in no time. The trainers go for $60 or so, the daggers for closer to a bill, but you buy the dagger in case you need it and then you build years of muscle memory screwing around with the trainer.
Folding: the Fox 499T
Hours of fun, and that's before you start watching the videos Doug Marcaida did with this trainer. Flip it, flick it, wave it, thumb it, just run the spine along something with a raised edge. This is another one you'll spin by the ring just screwing around with.
The Boker Plus trainer:
It's way heavy compared to a light knife, on purpose. Makes flipping it about kinda like the kettlebell version of playing with a butterfly knife. But it's awesome fidgeting.
If someone ever tells you 'quit looking at your phone' get this out instead and start doing flips and spins with it.
Anyway since you can go full speed full strength with a trainer when you want to, it ends up being a lot more therapeutic, like power fidgeting. It doesn't have that same thrill of 'omg I could cut the living bejesus out of myself' but I have learned that one can live without that thrill for extended periods of time.
So it is an option to take.
