I've got an identical Swaty like yours... mine's even complete with a chip on the back as well! For fun, I've taken one of my razors and solely using the swaty with it when it needs a touchup to see how long I can keep it going with just the swaty. The razor was shave ready last March, and I use that particular razor once per week. Every 6-8 shaves it needs a little touchup on the swaty... and I limit it to six X strokes.
Being that I shave with it weekly, that means I've got approximately 36 shaves with that blade so far. Not a lot, but by using the swaty in this fashion, it still shaves as if it were honed just yesterday. Obviously, I'm pretty impressed with this little hone. Who knows, maybe I'll get a couple years before I need to take that razor back to a full honing.
Have fun with it.
