Type L1 - 3rd variant, (S)chick injector blade and Schick Twin, shave 1 The third variant l1 razors were produced from 1980 - 1984. You can tell by the logo which is the same as on the Type N razors as seen in the picture below. I've never used this variant before and the first pass was with a (S)chick injector blade to figure out by feel what it was closest too. This razor as it turns out based upon that first pass is almost if not identical to a Type N1 and not any of the earlier Type L1 variants. Then knowing that much I decided to try one of these vintage Schick Twin teflon coated blades. First off this razor and the Type N razors in my opinion were designed for Twin blades and not single edge injector blades. The shave sucks with single edge blades but is totally different with twin blades, mild but deadly is how they shave. This shave was no different with these vintage twin blades though until I can acertain if the feel and finish is the same as modern Schick II twin blade in an N1 I can't say if these blades are any better or not than the modern Twin blades. I'll know that on the next shave when this blade gets loaded in my N1 for use. That will also confirm if this razor is identical to the N1 or not in the feel and finish test. BBS finished achieved though it sure as hell didn't feel like it would shave that close that is how smooth these blades are.
