Thanks for the advice on stropping first. I may practice using the B&B razor until I become proficient at stropping properly.

I've read here that even factory-honed blades require a proper honing to become shave-ready, and figured this "vintage" blade will no doubt need to be honed prior to use.
I can always practice on the B&B first, so if I get some education out of that crummy blade, at least I'll get some good use out of it, hahaha.

If I do it all properly, this Engels should produce a fine shave for many years to come.
