Some razors were made with guards that are removable. I have several. Some will have grooves cut in them to trim hair rather than to completely shave it off & others are there to protect the blade when not in use. I have both. Genco has one called a Safedge. I just realized last night that I have two Torrey's called a Little Guard that have guards on them.They all have small shorter blades on them but are nice little straight razor's. Below are some I own. The top one is a Curley from England which I restored. The next one is a Genco Safedge. Last is the Torrey Little Guard:
