I think I "Fixed" it.

My (BTI) Uncle Henry 885UH was a bit stiff to open.
An few hours making a new file dull, and polishing on a cheap Smith's fine grit pocket diamond hone seems to have "fixed" it. (note quotes.)

I can open the main blade now without having to changing position/grip, and without worry of breaking my thumb nail or ripping it off. (that would hurt! :eek:)
I think the backspring is around .002 - .003 inches thinner between the center pin and tang, than when I started.

Yes. I honed the liners and covers so the spring is flush with the blade open. It lacks being flush by a beard hair (maybe a beard hair and a half) when closed.

I still need to bend the main slightly on the Old Timer 858OT to clear the center liner.
I believe I'll wait until I get a small hammer for that. A couple light raps with blade supported by a "U" lock should do the trick.

Let the cursin', name callin', ridiculing, and gnashing of teeth begin.

At least now I can EDC that knife. :)

Whenever I need to lighten the pull on my slip joints half open the blade and stick a pick or anything that fits between the blade and backs spring and slightly flex the spring or leave it in ther overnight.

With my "luck" if I tried that I would break the spring.

Recently got a Marbles MR278 "Demo" knife. The hang-pack had all four blades half open. :(
The pull on the main and awl is great. Unfortunately, the spring for the can opener and screwdriver/caplifter was broken when I took it out of the package. (I'm surprised both springs were not broken.)
