Ok, you probably though this was a how to... but its not yet =)

I have an event I'm sharpening scissors for in the near future (a fabric store) and one thing I KNOW will come up is corrugated scissor sharpening. The problem is that I don't have a corrugator, so I have to rig one up! I normally sharpen scissors on the Twice as Sharp system, but their corrugator is very expensive.

Here is a pic of what it will look similar to... This fixture is by Wolff Industries that I will be simulating, but w/ the WEPS =)



I already have my WEPS mounted in a Panavise (this is an old pic, I have differrent rods now)



I recall curtis having made something similar to what I am thinking about... Curtis, post a pic again if you don't mind of your scissor jig that you made?

I am thinking of having a horizontal 1/4" round bar (same as rod arms on WEPS) that I will rest in between two blocks of wood... Then, I will rest another 1/4" round bar on top of the first bar, but perpendicular to it. I will have to figure out some way of attaching the two so that way the top bar can still slide horizontally as I move from heel to tip of the scissor blade. Then I can attach the corrugating file to my WEPS paddle which will slide over the second bar and then sharpen away! I will try to draw up what I am thinking soon...

Stay tuned!

When you say corrugated scissors I am a little confused do you mean pinking shears if you do; the part that needs to be sharpened is the face behind the triangles also do check to see if they work before you sharpen for some reason many people have very poorly made cheap pinking shears that simple do not work(they think anything over 20$ is too much where as anything much below 30¢ is too low a price)

. So either try them first or ask if they have ever cut properly .
To test them you need some good quality cloth and the cuts should be absolutely clean.
These in the picture do not work I have tried several times and they just are badly made; plus as you can see there is a lot of steel to sharpen so bear that in mind when pricing them.

Not sure if it'll help with what you're doing. For what you're doing I think you're on the right path, you're going to also have to have movement along the edge, so you can keep the stone perpendicular.

Thank's for pointing this out Leo, you are absolutely correct. I was talking to another sharpener a few months ago that said they have something like a 30% failure rate from the factory so you need to ask them "what's wrong with how they cut" and " have they always cut like that" and then also sample test a few cuts before sharpening. If they say that they have always cut like that then you might as well give them back because there's nothing you can do. Apparently the reason for this is because they are heat treated through "induction" at the factory, basically where they lay the edge on a super hot plate and heat just the edge. You can actually see how deep the heat treatment goes on some of them. but anyway, these are not what I'm talking about in this instance =)

Here is a pic of corrugated scissors... one blade is plane but the other is corrugated.

Exactly! Thanks Curtis... yeah, I just actually have to have mainly horizontal movement so I can fit the corrugations perfectly as I go down the blade. I will be able to tilt my panavise mount to mostly the right height/angle I think.

Ah I see micro serrated - normally only one blade is done so you can sharpen the plain blade only which normally ids enough .

Yeah, I've done that in the past but at the recent quilting guild they brought me some jacked up corrugated scissors that I didn't even bother with lol.

Curtis, it looks to me that for the added vertical arm you used some extra WEPS key stock . . . Hence bolts situated in the middle, or is there some other method in your :) madness :) !!!

Got'r'dun! Was easy enough to build... I can get any scissor angle I want and still use my stock arms (I put a hinge on the back side of the wooden "arm" and bungee'd the front). I also now have complete lateral movement for my corrugated sharpening (I will have to move the file 1/4" at a time down the length of the blade) so I can just pull up on the wooden "arm" and slide it down a bit. Then I used some JB Weld and epoxied the corrugation file to a WEPS paddle...
