I just spent more money than my first car cost (in 1975) to buy a Hinderer XM-18; Fatty, Spanto, blue G-10, 'battle blue' anodized titanium. It's a nice knife, though it is fairly heavy with the 'fatty' blade.

Like pretty much every Hinderer knife, the pivot screw needed some adjustment. It was WAY too tight. Opening the blade was a two hand job. Literally. I could open the knife 1/4th way with the flipper lever, but getting the blade the blade open the rest of the way required that I use my left hand to PULL the blade out.

I sure would like to have a few choice words with the imbecile who 'assembled and tuned' my expensive new pocket knife. He needs to be told NOT to use a pneumatic impact wrench to tighten the pivot screw. Idiot.

A quick look at the pivot screw, and the body of the pivot, shows that while the pivot screw takes a standard slot tipped screwdriver. the body of the pivot uses a 'security' screwdriver. Specifically, it takes a #12 'forked' screwdriver bit.

If you want adjust the tension on the pivot, you need this bit or screwdriver.

You can either buy one, or make one. You can buy 'security bits' from many places on the Internet. A local big box home improvement center near me sells several different sets of them too. I have a set of them I bought many years ago. It has various sizes of 6 different kinds of security bits. It has 4 sizes of the forked bits. The largest size in my set is a #10 forked bit. I used the #10 bit, though it is a bit small. The #12 bit is the correct size for the pivot.

If you don't want to wait for one to arrive by mail, you can make one. If you have an old slot tip screwdriver that fits the screw in the pivot, you can use it to make a fork tip screwdriver. Or, go to Harbor Freight, and buy the cheapest set of screwdrivers they sell that includes a screwdriver the right size. Keep that one, and throw the rest away in the trash can by the front door. They are junk.

You will need a Dremel tool, and some cut-off disks. Mark the center of the blade with a Sharpie, for the area of the tip you want to remove. If you have a bench vise, it will make doing this WAY easier. Use the Dremel tool and cut off disk(s) to cut away the steel in the center of the tip. Go slow, and try the forked tip on the screwdriver on your Hinderer knife. You don't want to cut too much metal away.

As these things go, this is the easiest type of the 'security tips' to fabricate. Now you can adjust the tension on your Hinderer knife. If you move the screw very much, it is a good idea to remove the screw all of the way from the body of the pivot, and apply a small amount of the BLUE #642 medium strength Permatex LockTite thread locker to the small screw. Do NOT use red or green LockTite. You will regret it if you do.

I use a penny, have for years. The Loctite they use is 242. Only takes a tiny drop. Some use teflon tape or Vibra Tite VC-3.
 
I could be wrong but is it not enough to only adjust the side of the normal screw? why need to adjust both sides? At least this is how I have been doing it and it always worked fine. Also, I read somewhere that loctite is not recommend by RHK. In fact, given the length of the pivot screw, I see it unnecessay as well.

My pivots (those without Loctite) would loosen up over time. Only takes a few minutes: just apply, adjust it to your liking, make sure it's centered, let it set 24 hours and you're done until you want to take it apart for cleaning. Rick has said Blue 242 is fine on the pivots, but not on any other fasteners used. I've had some of my knives delivered with Loctite already applied and some not, depends on the "assembler" I guess. The reasoning behind the pivot "tool" is to keep the pivot from rotating when adjusting, some knives do that.
 
I do this to every Hinderer I get, all of them are dead center and flip so smooth, if you plan to have more than one get the tool, its really great

Thanks for the links!

I love that guy Nick. Best Bronx accent I've ever heard. And his videos are 'no nonsense, no BS', too. I don't agree with every review, but he always gives the reasons WHY he likes or doesn't like a knife, in plain English. With a Bronx accent. But I respect him for making so many no nonsense reviews. He doesn't bad mouth a knife unless he thinks it really deserves it. A good guy, IMHO.:thumbup:
