I keep one of these on my desk. They aren't very sharp out of the box, but you can put quite an edge on them. Damascus steel is quite hard and holds an edge for a long time.
This is actual 512 layered Damascus, not just an etched on pattern like a lot of the so-called Damascus steel knives that are around.
The double edged blade is 6" long with 5" of cutting edge. Overall length is 11".
These come without a sheath. For the price, this is a very nice knife!
Check your local laws, double edged blades are illegal in some locations except for "theatrical" use.
