Unusual tanto in the shape of a dragon

[VANDOO]

HERE ARE 3 EXAMPLES OF UNUSUAL JAPANESE KNIVES THAT FALL INTO THE SAME CATEGORY AS YOUR EXAMPLE. #1 HAS A YARI SPEAR BLADE AND IS CARVED LIKE A HOKADO FISH #2. JAPANESE SHRIMP OR LOBSTER KNIFE.
#3. SAID TO BE A JAPANESE TEMPLE KNIFE. UNFORTUNATELY I HAVE NO BETTER INFO. BUT THEY FALL IN THE TANTO SIZE RANGE RATHER THAN THE SHORT SWORD SIZE.
