ESEE uses 1095 thrue out the whole construction of the knife it's self,hardness is about 55-57 HRC.And you can get them for I think around $40 to $50 on Amazon.com.If you want to see the capacity the knife can handle I would recommend you watch a youtube video on a channel call KnifeHQ.The video is called "ESEE Candiru:Field Test EXTENDED.I'm no expert but I fell the knife fits very well in to the roles as a kit knife and last ditch knife,or a fine detail knife or skinner.
