Tightening a knife handle

    I don't know anything about fixing knives, so I thought I would ask before I messed my old one up. I have quite a few knives, and most of them are old. One in particular has a mild (I think) problem; the handle is slightly loose.

    This is an old Marbles about 9 or 10 inches long with a 4.5 or 5 inch blade and either stag or bone handle covers. It is a beauty even though time worn and stained. I got it from a friend. I don't really care how the knives look when I get them, but once I do get them in my hands, I try to make them look better. Then, I keep them for my sons and grandchildren.

    The handle on this knife is just slightly loose. When holding the blade in my left hand, I can make the handle twist very slightly in my right hand. I would like to tighten this up; how do I do that? I don't want to damage the knife.

    On the back of the handle, everything appears to be held together with a nut with the tang right in the center. If I tighten this, will that tighten the knife handle? If so, what type of screwdriver?? do you all use to do this. I tried gently with a regular screwdriver but can't get enough traction to turn the nut. I didn't know if there is a special tool that fits over the tang and into the spaces on each side that would make this job easier or not.

    As you can tell, I know zero about how knives are made. I have had them all my life, but I never have tried making or fixing one. I would appreciate your help.

    Probably a spaner nut as on most Marbles.

    Has two recesses one on each side?

    I've made a few tools for these. Took a piece of scrap steel and measured the dimensions with caliper and formed two tabs that fit in with a Dremel tool. Clamp the tool in a vise or put vise grips on it.

    Yes, that's it. I took my camera home and don't have it with me at the clinic. I'll bring it back and do that, but I just checked ebay and found a picture of what I am talking about:

    Basically all you need is a piece of sheet metal that is notched to fit over the threaded part of the tang. You could do it with a cheap file.

    Try one of those tiny wrenches, like the one that comes with the dremel. Looks like it would fit.

    I just tightened up an old edge mark with similar construction. The spanner wrenches I had didn't fit, so I used a a small pair of needle-nose pliers to crank it down. Tight as a drum now.

    Just bear in mind that the nut will be slightly recessed when you're done.

    hi i have the same type of knife and was wondering how to tighten it once you have the tool. do you twist it or do you put the drill bit into an electric drill or by hand? if anyone could help that would be great. Thanks
