Forging Frame Back razor... fixed or removable blades?
I just picked up a frame back with removable blades from ebay. Never owned one before, but i was surprised at the smoothness of the shave.
Examining the razor its construction would suggest it be easier to manufacture than a regular concave straight. It interests me because I got four blades with the frame and I suspect there are three blades missing from a seven day set.
For a fixed blade the frame (spine) could be slotted just under the thickness of the blade, the frame heated so it expands, the blade is frozen so it contracts and the two fitted together. As the both reach room temp will form a permanent weld.
Or flat stock may simply be ground away to form a “T” cross section, hardened then finished… similar to razors made before concaving became the norm.
A removable could be made by slotting of the frame... a simple screw taped into the toe end for locking mechanism.
A blade pattern could be cut from sheet stock, tapered then hardened and tempered.
You could even have different profiled blades depending on your mood... Spike, Round, Square, Spanish, French... no limit... Did you say “seven days set”… “No problem you could have 24/7 blades right here…”
