http://jimsharp.blogspot.com/2010/03/... - A scissor sharpener called me and asked if I might be able to help him with a problem. He had made a mistake on one of his machines and damaged the blade of one of his customers shears. He said it was bent and didn't feel he could fix it. Seemed like a challenge, so I told him to send it on.

When I received it I saw what he meant! Boy was this shear bent in a bad spot!!! Right at the early entry! In fact, it was bend so badly it almost looked like the shear had a full bend of set in it, but in the wrong direction. I did my best to let you see this in the video, so watch if you haven't then read the rest.

As I said in the video, I had to do some more work to finish this shear; so I went into the sharpening training center and started to resharpen it. While doing so though, I noticed that there was a snake in the blade (this is a bend in the blade that looks like an S) about a 1/4" back from the tip. The blade also looked fatigued so I really didn't want to do a lot of bending on it because I knew it would break. I did a few test passes over my water stone after I bent as much of the snake out of the blade as I dared, but I still didn't have the shear set to the point where I could hone a consistent rideline without causing an unsightly wave. Fortunately, I had a trick up my sleeve, the Ookami Honing Blocks.

These blocks are much more forgiving than water stones and come in handy when you have a shear with inconsistent set problems. I worked the inside of the blades on these blocks, reformed an acceptable rideline, and then polished and reassembled the shear. It cut well when I was done.

All in all I had about 50 minutes in this shear. A little too long for my taste. If I had run into a shear that was damaged this bad in the field I would have sold the customer a new one. Remember, I often say that there's a big difference between scissors repair and scissors maintenance. Repair takes a lot longer and is less profitable and often a heavily damaged shear just isn't worth saving, but working on shears like this is also part of the fun and learning experience in the business of scissors sharpening. While this may not have been a profitable 50 minutes, imagine if I had been a sharpener trying to get into a salon and someone handed me a challenge like this. When I fixed it, do you think that would carry some weight? You bet it would!

Having the right tools and knowledge is essential if your goal is to become a successful sharpener, and two tools in particular saved the day in this case; the scissors press and the Ookami Honing Block Kit. Concerning the knowledge side of this equation, dealing with a problem shear like this requires sharpening training and/or years of experience. This kind of training is something I can help you with. So if you'd like to find out more about the sharpening training I offer, give me a call at Wolff at 800-888-3832 or email me at Jim@wolffind.com. Also know that I'm available for sharpening support as well. So please call or email me if you have questions concerning anything I did in this post, or with any other sharpening questions you may have.
