Remember how the AC Cobra was transformd by Shelby putting in a V8? I can't promise the same with this, but it's a simple fix for a problem. I happen to have a large stock of Feather AC blades, around 2/3 of them are the Professional Super blades which are ~0.06mm thicker and ~0.85mm wider. I preferred them in The Feather AC razor as they were more comfortable and less prone to cutting divots. I haven't used the Feather AC in a long time, and I did think to buy a Cobra to use up the blades. Periodically I use it for a few weeks and then go back to my straights. But Professional blade supplies are dwindling at home, so I thought I'd better see if I can use the Professional Super blades. NB. by mistake I did once jam one in and of course the edge of the blade sat up on top of the blade retaining bumps at one side (though not at the other, maybe a difference caused by uneven plating, or by play in the hinges of the blade support plate). Naturally it instantly gouged me. The razor needs a tiny modification to take one of these blades, and that is to carefully file away just a little of the blade retaining bumps. I have two Cobras, so I can alter one for the Pro Super blades and keep the other for the Pro blades. I used a square section rat tail file, and it took less than two minutes per side. Once you have filed through the chrome plate it seems to be brass inside as it files away quickly. Don't overdo it, as there isn't much metal in these little bumps that sit in front of the corners of the blade, and if you take it right off you will be relying on the projections on the blade support plate that sit in the elliptical holes in the blade to hold it in, and what's worse, hold it still relative to the razor as you shave. I don't think this will work at all.
Doing this alters the geometry of the razor in an important way: the blade edge is now closer to the lip of the blade guard and I would expect it to be more aggressive as a result. I expect some care and attention to angle will allow me to cope with that, but tomorrow I will find out.
Some pictures:
and a 100% crop to show the different blade widths, the positions of the edges relative to the guard, and the filed retaining bump:
Let us hope tomorrow will not resemble a re-make of 'There Will Be Blood'!
