I was trying to agree with Jim that (simple)specs don't tell the whole the whole story. The two razors I mentioned have a similar blade angle and exposure, but the design of the safety bar is dramatically different. It seems like this is a missing piece when somebody says two razors feel different. Obviously, your more thorough measurements should shed some light on why.Yes, but if two razors are nearly identical in specs, they should feel similar with all other things being equal (user, technique, lather, etc.). Right?
