Hi Andy,
I have designed a knife and someone is making it for me with material of my choice. I have attached (hopefully!) the design. The guy is not a professional, but the knifes he makes are stunning. It is costing me about £150 which is a lot less than anyone else that I have inquired with!
The Jacklore knifes seem to be bushcraft knifes. I am not sure if that design is ideal for field dressing animals...Presuming that is what you want the knife for.
Cheers,
Peri
