The blade is 1095 cro-van steel and it shares the same Grivory handle as it's big brother, the BK-7, and probably the BK-9. The blade is at least a quarter inch thick!! Monster! The blade measures 5.5 inches long and the knife measures 10.5 inches long overall. It comes with a hard plastic Kydex sheath with a nylon web belt loop that is removeable if you wish to use the integrated lashing slots to attach it to whatever you desire. It can also be purchased with a Heavy-Duty Polyester sheath with front pocket, similar to my BK-7 sheath.
If you prefer a leather sheath, they can be found on evilbay, where I purchased mine. The BK-2 sits deep within the sheath to eliminate a keeper strap.
1095 Cro-Van Steel is an easy to sharpen, plain carbon steel used in knife making. Proven to be one of the most popular steels used in KA-BAR knives. Here is an excellent review on YouTube.
I bought mine from Amazon as it was the best price I could find at the time. It's not cheap at $72.98 (free shipping) but you get what you pay for and it is made in the USA. It now resides in my GHB along with my Mora.
