Thread: Scandi Grind Angle?

Hey everyone!

Im about to craft my own straight razor blade. I don't have access to a sander so unfortunately i am doing it by hand and can not achieve a hollow grind. Considering this is my first blade I figured a scandi grind would be a good entry to do by hand with files and some sand paper.

Anyway, does anyone know of the optimal angle for this type of grind?

Also what type of files do you recommend? Brand? Series of coarse to fine?

Thanks so much.

It is possible to do a hollow grind with files. Somewhere I saw a kamisori being ground by hand, It may be worth looking into.
One of our members did a wedge blade by hand, It looked like a lot of work...
Good luck and sorry I couldnt help with your questions!

16 degrees plus minus a degree or two is a good angle for cutting hair.

These are knife grinds you are discussing




If you note the geometry of a straight razor you will see the grinds are designed to help with the honing aspect


The straight razor - Straight Razor Place Wiki


Keep in mind I think I have actually seen two True wedges, ever and they are really not fun to hone I think the Scandinavian grind might be even harder


There is a Japanese tool for Hollow Grind cuts by hand and I am drawing a total blank as to the name one of the other guys will think of it I am sure... It is a type of scraper


I am assuming you are already a straight razor shaver, the best thing would be to study the razor(s) you have now and emulate their designs first.. then eventually branch out into new design ideas

Not Dissin,but I cannot imagine why anyone would attempt to craft a straight razor with hand files

I would imagine the satisfaction would be just as great as creating anything with your hands.
A razor would be an extra special chore I suppose......

I think it might take a pretty good while. Might require more skill than doing it with power tools ...... certainly more patience.

Nah! Just pack a good lunch, breakfast, and dinner. A dozen MRE's will fill in! Get it on........Tom

I agree with the patience needed!

One thing with hand tools is a mistake is far less likely to be fatal. [Both to you and your work. ]

With power tools if you have an OOOP's chances are you are going to have to start over.

That would be a Sen. Different ones are used on all sorts of grinds. Even on wood saws.
