I really like:
1. The knurling
2. Fully disassembles to clean
3. The fact you can use this as both a closed comb and open comb adjustable razor.
Grip is one of the first things I consider in a razor, and if it does not possess knurling, it is basically a death blow for that razor for me. The Masamune held that distinction for me for some time, but I was lucky enough to win one in a raffle, and glad I did as it makes me reassess whether I completely write off a razor. I believe it is due to the Masamune I have being matte that helps with the grip. From what I see in the pictures, I like the knurling, and have no doubt I would find a secure grip with this adjustable.
I can't say that I am a fan of adjustables or open comb either for that matter, but the mere fact that you can choose between closed and open comb is intriguing, and one that I like. There always seems to be an exception to something even if you dislike it initially. I do have one open comb that manages to surpass everything else I've tried, and even allows my least loved blade, the Green Derby, to shine. That is my simple Gillette Tuckaway. I only reach for it when I have neglected my beard for too long and it has become very unruly, but it does a good job gently removing my scruff.
As to why I don't like adjustables I haven't found the answer yet. The blade feels a bit rougher than it should no matter what setting I've used it at. I've done Slims, Fatboys, and Black Beauties all to no clear favorite standing out as well as using a Mergress. The Mergress seems better, and while I like the idea of an adjustable razor to dial in what you are looking for that day, in practice it just doesn't feel right for me.
I hope that everyone that tests this razor enjoys testing it!
