I had a friend come by my shop last night , He brought a big heavy chopper made by condor tool .
It is called a "Boonslang" . My friend said the blade was bent , and did not hold edge very well .
He asked me if I could remove handles and straighten out the blade . Its supossed to made from 1075
So he also asked if I could clay the blade and put a Hamon on it . It was a thick blade almost 1/4 " at handle and about 3/16" on blade part . So I removed handles , and normalised it several times and also did anneal .
Pretty soon it was nice and soft , so I straightened it out and clayed it up . waited for it to dry a few hrs.
Started up the forge and heated her up to a nice color and non magnetic . Quenched it 4 seconds in water
no problem . When I quenched it in oil ( parks) I heard the terrible sound , at least three tinks .
I knew it broke . when I pulled it out it had four breaks nearly all the way thru . I was mad so I dropped it , shattered like glass . I havent broken a blade in a long time but this was a mess .
I can tell you one thing , it was not 1075 . Condor tool is using some junk steel ... I know my steel and
It broke like it was a full quench with something cheap . What was wierd it broke in the oil not the water .
I told him not to buy anymore of those blades . Not sure what happened . Maybe it had some hairline cracks I did not see ?? what do you think ???? I am inclined to believe it had some hairline fractures from using it . But, who knows . Cracking in oil but, no cracking in water was wierd ?? maybe I should have left it with the water quench !!
