Hello. A few day ago was my first shave with an SE Razor. I purchased this Supply SE from a member on the BST. It arrived with no blade installed and the two extra adjustment plates. 1 and 3 dots. I replaced the 2 dot for the 3 dot (most aggressive). When I tried one of the injector blades I could not get it to cut at all. Thinking I may have somehow damaged the blade I decided to insert the key and install a new blade pushing the other out. It still would not shave. It was like I was passing the shaver over my face with no blade. I ended up finishing the shave with the 1960 FatBoy DE. So anyway, tonight I decided to experiment. I took a brand new Feather Pro-Guard and measured it to fit and cut it off with a sharp scissor, which worked but was tough to do so I will need to find a better tool to cut off these blades. It worked! Is it possible I received a dud bank of new blades? They came with the razor in a white injector case. I don't understand why this happened and hesitate to buy more blades from Supply. But what a great two pass shave. I mean that was amazing! So smooth. Took a bit to get the angle right but once I figured that out it was clear sailing. I also didn't cut the blade exactly and a bit was hanging over the edge, that I can fix next time. So I have a few questions. 1. I did not like the grip and found it a bit slippery (polish chrome). Has anyone modified this handle in any way to achieve a better grip? 2. What are my blade options? Do I have to buy from Supply? thx
