Not that model, but I have a SB matte black. I don't use the head, which is quite mild, but I like the handle a lot, plated brass, and use it on other razors. Open comb should be interesting.
I've had mine for a while now, pretty much since it was released and it took me a few shaves to get used to it.
It's on the mild side of things, easily milder than a DE89 style head for sure, slightly more aggressive/efficient than a Tech.
But as ever YMMV.
I have several Yaqi razors.
I absolutely love the "scalloped head" which looks like an ej89 but it's so much more efficient.
The DOC is a tad on the mild side for me but it's definitely more efficient than a tech.
Quality is flawless and the handle design is wonderful & ergonomic.
I have 4 of the scalloped head razors in different colors (gunmetal, black, gold and chrome). Very impressed!
They are great value for money, quality and finish are excellent, never thought i would get rid of my vintage Gillette for a Yaqi, glad i did
