I recently aquired a Buck Creek mushrat and a German Bull mushrat knife. The German Bull add stated it was 440HC stainless steel. The Buck Creek knife just said german stainless steel. Both knives said they were made in Germany. Neither knife had 440HC on the blade and so far I haven'e found any info about what stainless was used. Is there info out there about this. Any info would be appreciated. RHensley
