Hey Patrick!
Most of the knife/cutlery stores in Manhattan revolve around kitchen cutlery.
There is Paragon Sports ... a big retailer selling all sports equipment, including outdoor sports and
water sports stuff. They usually have a good selection of knives and sometimes a small selection of
Hand Made knives. Several years ago (maybe more) you would even occasionally find a Randall or two
in their case!
Paragon Sports
867 Broadway (on or near 18th Street)
