Wouldn't work with my grinder. I'm currently researchingg my options in buying a 8 or 10 inch wheel.

Hum you might have to order a "no weld" grinder kit.

When I have a working 1,5hp fully functional grinder with 2000X50 belts already? No thank you.

Isn't it a little early for you to give out advice on what people should buy, given that you don't know the setup LX has, and you have no experience at all regarding razor grinding?

Lol. Yep sorry. I was assuming he was researching because he wanted something adjustable and was making a suggestion. Didn't mean to upset.

BTW,, the ratio is usually a range of 1:3.5 to 1:4

I agree that is a good approach. If you can't stand the thought that you might do all the work and not be able to use it, you can buy a piece of O1 in 1/4x1" big enough to make three razors for $15. Cheap enough to scrap after fooling around and learning, but on the off chance something might turn out it could be heat treated and finished.

Learning to shave and understanding the geometric considerations of honing is crucial as many others point out, but next on the list is getting some metal and starting to cut/grind/pound/whatever on it. What you do depends a lot on what tools you have access to and what skills you are starting out with. There are a number of helpful ideas in threads in the Forge section on how people have gotten a capability to hollow grind a razor or two without spending big $$$ on a pro grinder.

My modest efforts to make my first two razors are catalogued here:

with more extensive writeups on my blog:
Tooling Up: First two razors finished and in Use
Tooling Up: First homemade straight razors - out for heat treating

I made plenty of mistakes, but the resulting blades are useable and I will certainly do a better job next time.

Anyway, good luck!

Wow what alot of info! It seems I underestimated the straight!

I have some questions that come up again and again and are unclear to me.

1) the pictures sometimes show a hollow grind in two parts ie " a small belly in the middle, not a complete concave arc from spine to edge" what's that about?

2) the stabilizer half plunge cut. What is this for and is it needed for the function of the razor? I keep seeing modern razors without it?

3) can a ten inch wheel be used to make the complete plunge cut from spine to edge? Given that I would probably make a small round for the hone purpose?

Very nice looking razors holy and nice threads. Seems like you did alot of research too! How hard was making a shaving brush? Well done! Some really talented guys.
