Got a No. 4 flat grind, bird and trout flat grind, boat/Canadian Army and my all time favourite the large camper flat grind, had the latter for at least 17 years and through poor sharpening technique has lost a fair bit of the curve to the cutting edge. I love them to bits except the boat knife as I can't get on with the hollow grind. The only things I'd replace them with would be custom made versions of the no.4 and large camper, if I had the spare money.
You can get seconds which have tiny flaws, cheap from the company and kits which reduce the price.
The one downer is the sheaths are dear to buy separately as I'd like to get flapped jobs for the No. 4 and large camper.
