looking for service, blade regrind (broken tip) and lock-up on an old ZT0450

[Ritt]

This is an old ZT0450 that has sentimental value.
I broke the tip off (yes, I was prying with it, I didn't think it was enough force to snap it off, but it was) and would like to get it reground to a point.
Not sure what the deal is with the lock-up, but I can make the lock fail by spine-whacking, or just by holding it in hand and forcing it closed.
I don't know if the lock-bar insert needs to be re-ground or what.
Thanks for your consideration.

I'll move this to services wanted in The Exchange.

Thank you, wasn’t sure where to put it.
