BK14 vs. ESEE Izula. Becker wins by a mile. Longer blade and handle. 2/3 the price. No brainer.
BK16 vs. ESEE 4 vs. Cold Steel Master Hunter. Different animals all, but here goes. Deck out the BK16 in micarta scales and a snazzy kydex sheath and it will cost you the same or more as the ESEE. If you are OK with grivory scales and a cordura sheath, BK16 wins by a mile. $80CAN vs. $140CAN. No brainer. The Master Hunter is in VG-1 laminated SS, with kraton handle and an excellent sheath. $119CAN. Personal choice. Flip a coin. All 3 are excellent knives.
BK2 vs. ESEE 5. I wouldn't look at either. I just put scales on my Stanley crowbar and saved a lot of money.
BK7 vs. RAT 7 vs. Cold Steel Recon Scout. BK7 all the way.
BK9 vs. Ontario SP50 Gen 2 vs. Cold Steel Trailmaster. I'd choose the Trailmaster in the new O-1, but its double the price or more of the first 2. So...I'll take the BK9 by a nose over the SP50.
