but have enjoyed the results so much I thought I'd repeat it here...

While reading this thread I had a thought. What if I put a washer between the thumbstud and the blade? So I took off the thumbstuds and got out my collection of washers. For the 710 its a very specific size, its overall width needs to approximate the thumbstud width or it jams in the liners and sticks out over the spine of the blade and the hole needs to be just right to slip over the lip of the stud and it can't be much thicker than a half a millimeter or there won't be enough purchase on the threads. I was able to tweak a split washer to meet most of these specifications and attached it. Now the thumbstud on one side is raised just a bit above the scales. It makes a pretty big difference.
 
I've always wondered why they even put the thumbstuds on the 710.:confused:

I removed the ones on my 710 D-2, and open it with a "flick of the wrist.":)
 
Does your 710D2 have a lot of blade play caues mine does right after I tighten up the screw.

No blade play on mine either. I find it best to take the knife apart give it a good cleaning, lubricate the pivot and washers and tighten the pivot till you feel drag on the blade and then slowly loosen the pivot till the blade moves easily. I do use blue loctite as well.
