When making a knife you need to quench it in oil to harden the blade which you did great. Then you need to temper it back in an oven at about 400F for an hour or two to soften the blade a little bit so it won't shatter when you try to use it. By blueing one side with the torch you tempered it way too far maybe 500F-600F. You effectively ruined its hardness so unfortunately your blade could bend and quickly become dull during normal use. Otherwise a great looking knife!
