So my 70 year old uncle introduced me to safety razors over Christmas. Hooked me up with brushes, soaps and 8 different safety razors to try. My problem is with precision of the razors. Every single one that he gave me and two I bought have way too much play when I drop the blades in. I tried many different blades too. I use to be CNC tool and die maker and I can't believe how sloppy these razors are. Every single one has at least 0.020"-0.030" play where I can shift the blade to one side or the other. Every blade change I have to keep bumping blades to get center placement otherwise the blade is hidden on one side and cuts my face off on the other. I measured the blade geometry with caliper and they are very precise. Within 0.001. Why are all these blade holders so sloppy. Some locate blades on 2 pins and some on corners but all have huge gaps allowing for blades to shift even when pressed down (bent). I understand that these razors are casted and not machined but I worked in casting factories and we could always hold 0.003 on small parts like these. Why are they made with locating pins so undersized vs the blade locating slots. I don't get it. The razors uncle gave me were old school so I bought Viking Godfather and King C. Gillette. Same sloppy fit. Got fed up and bought CNC machined Henson razor. This one had real precise blade placement but is so mild I can not shave with it as I shave every 3-4 days and need more aggressive geo. I love this new to me style of shaving but blade changes are making me down right angry with sloppy fit. Also the weight of the heads are way to heavy for me (plastic disposable shaving for 30 years). I found the lightest handle and old Gillette head that is super thin and light but the blade shift is horrible. Not sure what to do???
