    I am trying to decide between one of the SP 50 series ontario knives vs the becker bk9. I like both of them but I wonder how strong the tang and tang knife junction are. Does anyone have a picture of the tang or can someone comment on the tangs and if you think they would be a tougher or weaker knife than the BK9?

    Thanks!

    I'd say weaker than the BK9 but plenty strong. You aren't going to have an issue.

    I've never heard anything bad about Spec Plus knives.

    This ^^^. I used my SP50 hard. It's solid. Buy the one you like most. I don't think durability is a concern.

    Two different animals guys. The Ontario is 1/4" thick 5160 spring steel. The BK-9 is 3/16" thick 1095 Cro Van steel. Both are excellent knives. Both are excellent steels. Only you can decide what is right for you. I have an SP-51 & an SP-53. They are HEAVY DUTY & also HEAVY (think quicker fatigue, i am 50 yrs old). The SP series are not a full width tang, but they are full length tang. But seeing as they are 1/4" thick, i doubt you will have any trouble. I have pounded mine into a tree & stood on it. I weigh 220 lbs. The BK-9 is a full width, full tang/extended tang. I would trust my life with any of the 3. But the best "all-around" one is the BK-9. It chops better than you possibly think it could. Add a choil & some jimping & it will become your go-to knife like mine has. Get you one. You really can not go wrong with any of them.

    Hey thanks. I don't know about that tang, kind of looks a bit small. Makes me lean toward the BK9.

    I have heard similar sentiment from many people, that they both excellent. I am looking for a heavy all around knife that could act like a machete when I don't feel like bringing one or that can be used as a fighter if the situation arose. I like both knives, I think the thing is, I like the spring steel and the thickness of the ontario, but I like the full width and length tang of the bk9 and the ability to take the scales of and clean it if needed (and additionally I know the bk9 won't have any rattle with the handle) where the ontario could potentially become loose, in which case I can't really replace the handle.

    Do you attribute this to inferior heat treat of the ontario vs the becker? Since most people say 5160 is the better steel.

    Better steel no, tougher steel yes. BK9 is a step up in quality imo, and 1/4 thick with that blade length is ridiculously heavy.

    Wow the Becker is heavier! Thats really surprising. Actually you know I bet its because of the more substantial tang.

    It is also a little wider i think. Too bad you were not close, i'd let you try them out in my back yard.

    Heh thats awfully nice of you, I regret I'm not a neighbor.

    Correct me if I'm wrong but the SP50 is thicker than the bk9.

    No, I'm just guessing that the Ontario tang would break under less load than the Becker if you used a machine to break both.
    If the Becker tang gives you more confidence then buy that one. I prefer the 1095 Cro-van to 5160. But again, both are good. And I own both the BK9 and the SP50. :D

    I thought about beating on my spec plus then realized it's 440c

    Not sure how tough it is.
