Fixall,
On doing the shoulders the temptation is to file them at a perfect 90°. This isn't as strong as a radiused corner. It can cause a stress riser in both HT as well as in use.
Try this next time:
1) After clamping the blade in the vise, use a small chainsaw file to make a rounded corner.
2) Then use the flat file to make the flat shoulder.
