I used a Pal, what appears to be a carbon steel, razor blade in the Gem Junior Bar today. It is the first time I have experienced a difference in SE blades. I can't say I enjoyed it. It wasn't nearly as comfortable as the SE blades I've bought from CVS and Walgreen's. However, it appears to be uncoated. I guess I can experiment with stropping this blade.
I really like using the larger wooden handle I robbed from the New Gem stropper.
