Quote History Quoted:
SE blades that aren't purely intended as industrial scrapers or box opener refills are rare, when I went looking I think I only found one or two options. The Injector blades are similarly rare.
With that ball end razor, you may want to put the handle aside and just use the head. The ball end handles have a tendency to split longways and/or lose the ball from the end, it's just pressed in. They made the same razor with a thicker single piece handle, that's what I use and those handles are a lot more durable.

Simply untrue
Shark, Derby, Permasharp, Feather, Gem, Bluebird, Racer Saloon, Lord, Sharp.... There's more but I think I've proved my point, all make SE blades
ETA your favorite DE can be your favorite SE with 20 seconds of your time and a pair of wire cutters!
I'm sorry for your loss but I hope you have fond memories of your grandpa every time you use it!!
