Blade 'crinking'

Post by bearblade »

Well, I'm brand new to the club, this is my first entry. I have ordered knives on the net, styles I feel good holding, but on some of my folders, they have been 'crinked' wrong so they leave scratches from blade to blade. As stated, I love to hold them so I don't want to get rid of them, but I wonder, can I vise them and try to bend them minutely, but I suspect it can't be that easy, nothing ever is. All input appreciated in advance, help please!?!

I'm Wes, or 'Bear', look forward to your replies.

welcome wes! re-crinking the blades is very chancy with a finished blade. they can break very easilly. crinking is done with a hammer. the vise might cause the blade to snap. good luck.

Hi Wes, as Jhonnie already stated, krinking tempered blades is a gamble, I have crinked many american made knives without problem using both a vice and a hammer. GBut german made knives like boker, buck creek, german eye, bulldog, ect I would never try becuase they are tempered much too hard and will definately snap. If you try and you use a vice put the entire blade in the vice all the wya up to the front of the plunge lines and crink right at the tang be sure to pad the vice jaws with wood or leather so you don't marr the blade. Also it's a good idea to use smooth jawed needle nose vice grips on the tang and use those as your lever instead of the handle, becuase if you use the knife's handle you taking a big chance of screwing up the pivot.

I've experienced the same thing a few times, even on a Swiss knife - a Wenger. On one knife I remember ending up with a loose blade when I tried to correct the problem. Probably just me and my ten thumbs :oops:, but be careful! :)

In regard to the question of crinking folding knife blades. When I worked for schrade-walden we used to call it blade setting. We had two piles the pile that broke and the pile that didn't. If you are a knife collector or owner and need to decide whether to crink or not to crink here is the test to give your knife. Take a piece of notebook paper and slide it between the blade or the scale and the to blade that you think are too close, if the paper slides without touching the blades when it is closed you do not need to set the blade. If the paper does touch when you slide it between the blades or scales,do the same thing! Nothing. We all must learn to live with imperfections. I was discussing the blade centering subject with Bill Howard of Great Eastern cutlery and he said when the blade isn't centered it means nothing. Your wife isn't perfect either just love your knife like you love your wife, they will both still cut the mustard.

Fred; thanks for posting and welcome to AAPK! ::tu:: ::ds::

We here at AAPK have great respect for those who actually worked at the factories that made our favorite knives, and we love to hear your stories and gain knowledge from your experience.

Pardon my ignorance, but I assume that all crinking was done after the knife was assembled? And also, were the blade tangs annealed after hardening/tempering so that the softer tang would enable a slight bend when crinked?

I have another question related to knives like stockman patterns, where two small blades shared the common backspring - were the blade surfaces asymmetrically (or offset) ground, so that the two "mating" sides, say one side of a sheepfoot and one side of a spay blade would fall past each other more readily without interference?

I don't disagree with anything that has been said thus far. I know there is a really good video on this subject somewhere on here. but can't find it. Here is a page on this subject from another site including a video on crinking a blade. I have tried this before and had some success with it. Do not try the bending with pliers method. It has never worked for me.

HI Fred, and welcome. Below is a link to one of the threads on AAPK regarding crinking. I agree with everything that has been said. I have mostly had success with crinking, when it was absolutely necessary. However, I have broken some blades too. Use the setup in the diagram and use a lot of light taps. Quit when you have achieved the objective, i.e. blades are no longer rubbing. Every time I have broken a blade, it was on that one last tap to get it perfect. Quit when you are ahead!!!! :D

I understand why folks would say that the blade rubbing is not important. On the other hand, if a man buys a knife, he might want it to be made correctly. If something bothers a customer, then it does mean something.

Blade rubbing does not bother me. Nor does a blade that sits a bit off center in the blade well. What I hate is a blade that is not straight when open. If I sight down the blade well and the blade skews off to one side or the other, then I will not carry it: the knife is consigned to a display or drawer. I have plenty of knives that are straight, so why would I want to carry a knife that annoys me? I can see why someone might feel the same way about the rubbing.
