I'd like to learn more about these straight razor "type" razors. Where should I start? https://www.theshavedenshop.com/images/source/TSD-Lanolin.jpg
Yep, a kamisori. Kamisori is just Japanese for ‘razor’, but in the west the word is used to describe the traditional Japanese razor like this one.
If you are only interested in that type of razor, you've gotten good replies. If you were more interested in a broader look at these razor types, especially disposable blades types, this was/is a good primer, though now very outdated. https://theshaveden.com/forums/threads/shavettes-the-truth-about-disposable-straight-razors.29942/ And of course, true straight razors have their own section of the forum, so no need to point out an article type page for them, even if they could be summarized in one article.
One question that every kamisori user has to answer is, ‘What do I do with it when I’m done shaving?’
This would be ideal. https://www.ebay.com/itm/Three-Kami...3-7650-437c-b5b4-cf1977954807&redirect=mobile
