What is the grind of a straight razor referring to?

Expensive replaceable cartridges are only made to offer 4-6 "good" shaves for most people. Sorry - that's the deal. You can strop cartridges (in on direction only) on denim and pick up maybe a dozen more - search youtube for examples. I finally gave up on carts and moved to a straight razor; a razor or two will last for a lifetime with good care. There IS a learning curve for safe use and maintenance procedures. Find a straight razor forum if you want great shaves and good advice on what to buy, what not to buy and how to be safe.

Double edged safety razors are also a very good alternative for better, smoother shaves and WAY less expensive blades. Same advice - find a razor forum to save money, buy right and avoid nicks.

First you need to strop the razor on a daily basis, you should also horn your edge every once in a while. Moreover, you need to prevent corrosion from forming on your razor. In order to do so, you would need to rinse your razor after each use and allow it to dry properly. You should also keep the blade well lubricated after each shaving session.

All razors lose their edge over time even with daily stropping. Honing reestablishes the fine edge of the razor by removing some of the medal some of the metal from the razor. Honing is a necessity when it comes to razors.

The temper of the razor is the heat treatment imparted to the blade during its manufacture. Razors can be either hard, medium or soft temper each with its own benefits.

The balance of the straight razor refers to the relative weight and length of the blade as compared with the handle. A straight razor is properly balanced when the weight of the blade is equal to that of the handle.

The key things you need to consider when you buy a straight razor are its balance, its temper, the size of the blade, its grind, the finish of the razor and its style.

The one big advantage of the straight razor is that if you take care of it properly it can last for a long time unlike modern razors which you simply throw away after a few shaves when they come too dull to use.

The straight razor handle usually made of hard rubber, plastic, bone and even metal.

A straight razor is a shaving razor constructed of a long steel blade attached to a handle by means of a pivot. A straight razor is a classic shaving method and nowadays it is less commonly used since the invention of the safety razors.

Wet shaving at its simplest, is just that - shaving with water, a razor blade, and some sort of lubricant (lather, soap, etc.) on your face. Men have shaved this way for centuries, starting early on with a sharp knife or stone, progressing to the straight razor, safety (double-edge) razors, and eventually cartridge razors from companies like Gillette, etc.
