No ,,never seen one before, not familiar with Muhammad, but I've only been here 3 years.
I have limited time & resources like most people, so when I indulge in the hobbies that I like, I stick to reputable vendors that I know. I learn of reputable vendors by listening to the advice & reviews of members on SRP. Since I've never heard of Muhammad & his razor skills here before & based on the pictures provided,,,I'll have to pass on these razors.

As far as purchasing them as a gift to someone, well,,I would not give one of them to a new straight razor member because the razors might not be any good & the new guy gets a bad experience right from the start.

If they interest you & you have the money to spare, then I suggest you get one & give us a good review on it's performance.

or,,

Get one & give it to one of the veteran members here for them to review & return to you when the review is over.
