A straight razor must be sharp out of the box - I have no doubt Spyderco cant do that.
Second, I prefer a carbon steel (e.g. Maxamet) which gets really sharp.
Carbon, rusting steels are sharper and easier to sharpen.
I sharpened my straight razors and also get them professionally sharpened and still do not get a smooth shave.
(I prefer double-edged razors.)
Please not H1.
This is the perfect steel for salt water activities but not for a straight razor.
If you shave with salt water you will probably use a shark tooth or turtles armor as a razor
H1 seems too soft, IMHO.
