Dave … what do you use as a cutting surface that allows you to do so much so fast? I’ve been using a self-healing hobby matt … but I suspect it “grabs” the round knife too much and really slows things down (plus it seems to make the process more dangerous - those round knives are SHARP, definitely best not to put fingers in front of it …
I use a Hydroma cutting board and have for years. While I do have those self healing mats ya mentioned over my workbench, as ya can see, I can't cut on them either. My knives get stuck in them. Hydroma is a German deal and was originally designed as an industrial clicker/die cutting base. We have several of them. One I use as my cutting board. Another for all my punching needs and a third used as intended in our cutting press. Just Google Hydroma cutting boards and ya can find them, although some leather supply places sell em too.
I expect the knife to cut through the leather in one pass and kind of skate across the cutting board without getting stuck. The Hydroma accomplishes that. The edge of your roundknife needs to be very polished to accomplish that:
These bad boys are just across the shop and I will stop when I feel the edge dragging and give it a quick buff.
I was working on a batch of sheaths and holsters. This is what I'd cut out the evening before before I shut the shop down, two sheaths and four holsters:
This is what I had to do yet:
The speed with which I cut never really occurred to me, I am interested in efficiency though. So I thought I'd time it. I cut out 30 pieces here they are with last nights work:
I started by going to the buffers real quick and then started cutting. I did stop to take all the pics for this deal too. Total of 45 pics were taken. Bout half way through I went to the buffers again for a quick touch up. While running this little test I did come across this one sheath back that had what looked to me like dried sweaty palm prints. I saw this when I first unwrapped the side and also when I was laying out the sheath. I wasn't worried though as I have the cure. Ya can make them out in this pic:
Little bit of this on a paper towel:
Let er dry and palm prints all gone:
So time expended cleaning this one, going to the buffers twice, cutting out 30 pieces and taking the pics was 31 minutes. That included looking out the shop door too.
Anyhoo the Hydroma is really the way to go for me with a sharp roundknife. If I can cut on those self healing mats my knife ain't sharp enough. Course about that time my son showed up and said he's ready for a new pair of shoutgun chaps and one of his feed bags got broke too:
Our stuff don't get babied much.
