Roll cutter blades

Is it possible to somehow sharpen roll cutter blades? I know that sounds like a cheapskate idea I just can't get to a store that has them at the moment so I wondered if anyone had tried this.

Thanks for any info

BPC, if you can somehow mount them onto the end of a wood dowel, and centered, you could potentially chuck it in a drill and spin sharpen it against maybe some 400-600 wet/dry sand paper ?

Yes... it can be revived somewhat with a loaded strop and patience to work around the blade. It can also be done with fine (1500 or 2000) sandpaper, using the sandpaper like a strop on a hard surface. Don't hone or grind freehand because you risk altering the circumference. A stropping motion is pretty safe, I think. You should be able to see the portion on the blade's bevel where you have worked quite easily because the steel isn't very hard and scratches/shines up when worked on. Just be careful you dont cut yourself when you do this...

Here is how I do it .

I almost had to figure this out the other day, when luckily I found my new blade. But this is great info to have. Thanks for posting this.

I have put a bolt through the hole in the blade (i think it was 8mm) and put a nut on it, chucked it in a drill and spun it against a strop. However now I use a tool made to sharpen the rotary blades. The one I have was $10 US. It is easy to use and seems a little safer. The one I use is like this one, just a different brand: https://www.amazon.com/Quilting-Bear-Premium-Universal-Sharpener/dp/B07K7P186F/ref=pd_lpo_201_t_1/143-5286271-0312439?_encoding=UTF8&pd_rd_i=B07K7P186F&pd_rd_r=5bdb1e35-32cc-4600-9091-bfcd7feea2d1&pd_rd_w=V7yYF&pd_rd_wg=WhqCk&pf_rd_p=7b36d496-f366-4631-94d3-61b87b52511b&pf_rd_r=2AWQRFE1NA90ZK7RXCBV&psc=1&refRID=2AWQRFE1NA90ZK7RXCBV

Thanks TreeFork for sharing.

What the heck??! I didn't think possible. This is the THIRD hot tip for my SlingBrain in just one week???!!!

Cool info and great video. This topic got brought up in perfect time, I just ordered a rotery blade today should be her monday the 29th. I also bought 200 1/2 inch steel ball bearing ammo. :imslow:

I use the stropping method like @urbanshooter.

A sharpie mark on the blade helps me track my progress.

It's just easier to use tubes! :rofl:

Treeman great video. I like your way better than mine. I bolted mine down to a piece of 1x4 with just the edge hanging over then used a strop on a board kinda like you'd use a rasp or file. Cardboard wheels?? Totally new to me! Get them at lowes?

Im so glad my old man taught me to always ask questions. On this forum it always gets great topics going with much discussion of different methods.

Loving the exchange of ideas here, I'm an engineer at heart lol.

I'm sure someone probably already found these, but if not, I've used rotary cutters forever and found these a few years ago. They fit my Olfa 45mm cutters and cut well and are so cheap that there's almost no need to even bother sharpening. I always cut on a 1/4" thick LDPE backing board so the blade never rolls across anything hard that will dull the blade. Just a fraction of the cost of new brand name blades.

Perfect! I should get my 1st cutter tomorrow.

Now im almost wanting it to get dull. Ive got a lot of cutting to make. Which means more bands. More shooting. More destruction. More fun! Come on tomorrow!

im going to shoot you away.

Yeah those are actually pretty good blades in my experience. I still resharpen my blades but that is mainly due to having the tools set up to do so already
