You will be fine. It's odd, but there are very few bad American made razors. Despite the cachet of European stuff, most of the American razors shave just as well and tend to be much cheaper. There are no apparent issues with the spine or the edge so it should hone up just fine. The crack in the tail is quite odd, but it does not extend to the other side so it should be fine. If you are going to have a crack in ANY part of a straight razor, the tail is the best option!

Now, on to the other stuff.

You absolutely positively need a decent strop. Now. A straight razor's edge must be re-aligned with stropping. That is, with proper stropping. Bad stropping can have the opposite effect and trash an edge surprisingly quickly.

You need to have your razor honed. If you are smart, you will have someone else do it the first time. That way you can see how the razor works for you. Like riding a bike, it won't be pretty on the first try. Read the beginner's section for a lot of tips on what to do and not do.

You do not need hones yet.

You do...hopefully get the point. Don't jump into the deep end of the pool yet. See if the razor is something you want to stick with or not. The reality is that a lot of people fall in love with the concept but don't want to bother with the effort. It is effortless for me NOW but it took quite a while. Some people just don't want to go through that process.

If you might be one of them, consider a safety razor. It is much less effort to maintain, as in just changing blades (that only cost 10 cents).

Whether you stick with the straight or decide to move to safety razors or descend back to the depths of depravity and use a cartridge razor, consider trying q decent brush and a good soap. Any shaving method will work better if you put in the effort to make a better lather.

End of lecture. Good luck and have fun with your Shumate and welcome to a great forum!
