Here are photos of some of the knapped blade knives I have available.
Most of them have obsidian blades. Some are agate and others jasper.
The white bladed knife is knapped from fossilized coral. These are strictly art deco knives, although they could be used for a letter opener only. While a shard or chip of obsidian can be sharper than a surgeon's scalpel, the blades' edges would be too hazardous to use in the field or kitchen if left without further snapping.
A tiny fragment of the stone is likely to break off when cutting meat or other edibles. Instead of antler, one knife has a very dark green buffalo horn handle.
