I've been experimenting a bit with the Enders (and I did acquire an Enders Speed Shaver to add to my Enders Speed Razor
).
Something positive:
One of the flaws with using injector blades with the Enders razors is the blade itself - I've tried several injector blades and they just don't seem to match up with the best DE blades for sharpness. However, the Feather AC blades certainly do! They are pretty much better than any DE blade for me. So, I decided to cut one down to size to fit the Enders.
It really makes an already good razor better. It is so smooth and makes the razor more efficient. I definitely will use these blades more in the Enders.
The process is simple:
1) Using the Enders Blade as a gauge, cut down the AC blade to length with a good pair of snips. It should not bend or deform if you're using good stuff. I did it while I held the blade in my off hand.
2) Round of the corner of the snipped end to match the curvature of the other end. I used a diamond hone (because I have them), but sandpaper should work.
The process takes about 30 sec.
Something negative:
I've found that using a dulled Enders blade as a shim can lead to rust. This could be because of galvanic corrosion or maybe it's just because of the water trapped there. The Enders blade is probably not stainless and that's the issue. Short of taking everything apart after each shave and drying it, I can't think of a way to avoid it if you use a shim. It is making the commercially available shims look better all the time.
