Thread: Ever seen a ground frameback ? O_o

That way he obtained razors that, according to testimony, performed better than rattlers for a fraction of the price of a regular razor.
They were deemed quite qualitative by the peers of the time.

Oh, in case you wonder, the scales have been certified as tortoise
