I found one major difference which would make the LB7 stronger than the LB8 and that would be the lock back spring pivot pin. The LB7 is made of steel and the LB8 appears to be brass so it can be rolled to conform to the bone handle. Now, I never seen an LB8 failure until I found one listed on e bay with a broken lock spring and it appears the brass pivot pin has failed. I like both knives and the only knives I have found to be comparable are Bear & Son which I found at my local hardware store. I got to hold a Bear and Son and they aren't as heavy as Schrade thinner brass and less handle rivets but very high quality. Anyone else know of this company? All their stock is made and assembled here in the U.S..
