Aside from the bar stock issue it could be down to how big is the heat treatment oven? Although I have seen a post where the Custom Shop did a fairly huge Bolo/Sword...it is on here somewhere...so the Kukri may well be do-able...the price estimate quoted was $300 an inch and this was well over 10 inches...more like 15? Anyway the width of the stock used there would have enabled a kukri to be made. Also....unless they sent it off to be heat treated elsewhere as a one off...they have heat treatment facilities big enough as well.
