Hello all,
As a new T4 owner (~2 months), I’d consider myself somewhat happy overall with my purchase. While I feel it’s a fine machine, I think the amk-75 would’ve been a better choice. But I haven’t added the Japanese stone, yet, so I’m still hopeful.
I have a question about a specific knife, though. I own a spyderco parata.
I cannot for the life of me figure out how to jig this thing to where I can maintain a reasonably consistent angle. Any suggestions?
Micha is right... the collar on the Tormek Knife Jig won't work well with that knife. A "pivot collar"... something that reduces the sides of the Stop Collar is the easiest way.
There are a couple of "commercial" options available:

You can also use a shaft or stop collar like this:
https://www.mcmaster.com/shaft-collars/clamping-shaft-collars-9/system-of-measurement~metric/for-shaft-diameter~12mm/will also work. Basically any way to reduce the sides of the collar on the Tormek, so you can consistently and smoothly pivot the knife. (For another example, some have taken the stock collar and cut it down).
To help set the knife in the clamp, draw a line across the stone, then set the knife in the clamp so that when you pivot the knife, it stays close to the line... so that when you sharpen, you'll have a consistent angle/edge.
There are other options, if you're experienced, for example you can remove the stock stop collar and sorta freehand it,,, the key being stay at the same location on the wheel.
This picture shows an example...
... the bottom three, with the collar on, the knife won't stay close to the line, the top three, with the collar removed you can stay on the line. (Which brings up using a laser)...
Welcome to the rabbit hole!
