Hi Roy, I have no issue with your blade or dagger. I have handled 100s of SA since I began collecting in 1982 at local, small Toronto area shows and I have seen this blade configuration previously. I can not of course say that it was the same maker. I am in agreement with Paul on this one. I have no issue with this dagger. Collectors may not pay a premium right now due to the lack of information but in 10 years this dagger will be a very desirable item when it is pronounced to be "fine" cheers, Ryan
