Thank you gentlemen, I appreciate the kind comments - and I am glad you like the knife. Perhaps a few remarks - Hans, the handle does taper out a little towards the end but it is still fairly slim - I think the blade makes the handle look wider than it is. I do have large hands but even so, I think the knife will be comfortable for most men.
Ron, thank you for the information, I really appreciate it. Brilliant to be able to own one of the originals! I can just imagine what an authenticated knife like this must be worth :-) More than the money, that is for sure! Also, thank you for the information on the steel - 1/5th (5mm) is the closest I had to 3/16th (4.8mm) as I'd read somewhere this was the steel size used. I did think it a little "robust" for a bird and trout knife initially, but the grind worked well and is actually very clever - the long swedge Mr Randall added to the top has the effect of thinning down the tip and increasing the cutting/slicing/filleting ability of the knife, while the "ridge" formed between the bottom and top grinds helps the knife retain a lot of the strength inherent in the thicker steel.
But, seeing as it was an original that inspired me, and as I have some 1/8th on hand, I guess I have no option but to make another one, more true to the spirit of the original...:-)
