Thread: Newbie Questions and Hello

Hello! I recently got bit by the sharp bug and have been making knives and a few straight razors for fun. Everything up to this point was kinda having fun, but id like to graduate to having fun and making quality+usable tools. I started doing the SR's to accommodate the size of my forge for heat treating, as the stock needs to be much less than 2" - the more i read about straight razors and kamisoris the more i fell down the rabbit hole and its really sparked my interest.

I designed a few SR last night and was going to get some time today to cut and rough grind but started reading about blade geometry and opened a can of worms. Compound that with poor math skills and now my head is spinning.

I watched Lewis Razors video "Some thoughts on razor design". Seemed pretty straight forward with thicker pieces of steel (1", 1/4" ect). I'll be using 5/32" 1084 steel, after doing the math it seemed the height of the blade would be rather small. Trying to compare that to the "standard" 5/8, 6/8, 7/8, 8/8 has confused me further.

Is this right?: 3.5 x (5/32) inch = 0.546875 (13.8mm)

13.8mm seems a bit small for the blade

Any tips or tricks here would be appreciated and I apologize in advance if this is already on the site somewhere, the search wasnt providing clear answers. I also appreciate and look forward to responses and more lurking on SRP.

TL/DR
Could a 5/32" thick steel be used for straight razors?
Could i make a 5/8,6/8,7/8 etc razor with this thickness of steel?
Will razors work if the 3.5 to 1 geometry isn't used?
