Hello Dave,
thank you very much for comment!
No, it's a different animal, similar purpose but would be called with an other name. The seller from your very nice mead peek nok is a very close friend from me and of course I've shown him my knife already but he can't tell me the name of my knife but will ask a Thai friend so maybe I will be able to provide a name for this knife in near future. The blade tip of my knife is the so called hua bua tip.
Best regards,
Detlef
