It is my understanding that the 560 Ti uses the same blade blanks as the 110 Series.
If you open the 560 Ti and a 110, and lay them on top of each other, they match in all dimensions and pin locations.
(except thickness of the handle & weight)
This one I picked up on another Gun Forum in their Classifieds several years ago.
I recall paying $75 for it. Plus I bought a natural leather sheath for a 110 from Buck.
The Titanium handle isn't in bad shape, the blade has some scratches on both sides.
The blade hinge pin is tight as is the blade lock back feature.
I recently gave my adult son my Buck 110 which I recall being my first purchased deer hunting accessory almost 50 years ago.
When I sharpened the 110 before sending it off with my son, I also sharpened the 560 Ti.
While researching the production date on the 560 Ti, I made the mistake of checking the value on several nice collectable 560 Ti's.
Yikes! They are bringing huge money for nice condition collectable examples.
Since this unit has some scratches on both sides of the blade, it's just another working knife for me.
32 years of use/abuse, other than the scratches in the blade, it is still extremely serviceable.
I wonder if Buck would put a new blade on this knife using one of the newer "super steels" such as MagnaCut, S30V, or S35VN?
Buck offers multiple variants of the 110 using all three of the above mentioned super steels.
I guess a phone call can't hurt. Except for my wallet.
The original slim/lightweight Buck 110.
