No more air bubbles. Less than 1%. I knew Dan would address this. The only reason anybody buys a Dan Busse Scrap Yard knife is the extreme toughness of his steel. We can order prettier knives for less any day of the week. I am glad the problem has been corrected. I have been in the 99% of customers that got good steel. But if my "safe queen" extra DFLE should have a problem, I know Dan and Patti will make it right. I already beat the heck out of my DF and user DFLE, and they have been tough as jack hammer bits. Glad to see they are already at the new address. I'm looking forward to the increased prodution and some new stuff from SYKCO.
