twist the base and it opens to take the blade.

I remember those. Another one I had adjusted the blade to 9 different angles depending on how deeply you wanted to cut yourself.

I rediscovered a Gillette Atra Plus in my junk drawer and found Personna cartridges on Amazon that fit it. You can get 50 for $6. Couldn't get any cheaper without going to a straight razor and a strop. ;o)
