    Default making an ulu knife

    started making this Alaskan ulu knife today from an old saw blade, all was going well except the sanding belt caught on the edge and threw the knife back at me , cut an artery in my wrist and a large cut longways down my thumb. (warning gore alert)......bob

    Nasty. Thanks for the warning though. I hope there's no permanent damage and you get back into the workshop soon.
    What type of belt sander do you have?

    Hi Bob, Guys,

    I agree with Chris, very nasty !

    It just shows how quickly something can turn on you and cause injury, I hope that it heals rapidly.
    Best Regards:
    Baron J.

    Ouch!

    I have had similar things happen with smaller parts grabbing on a linisher and flipping in my hand. Not with the same consequences though.

    Get better soon.

    Thanks for the pics!

    Girl, I don't wanna know about your mild-mannered alter ego or anything like that." I mean, you tell me you're, uh, super-mega-ultra-lightning babe? That's all right with me. I'm good. I'm good.

    The curved shape is best completed by "dragging" the cutting edge.
    That is, with the belt moving away from the cutting edge.

    I made a leather cutting knife of the same shape as an Ulu and found that out.

    No, I did not cut myself, but ruined a belt and a idler wheel.

    May you recover quickly, Robyn.

    That is a good point why is it that those of us who are knife makers grind towards the edge when everything that you have ever been told/learnt tells you it is a accident waiting to happen.

    I believe it has a lot to do with the lap of the belt joint .Some belt joints are not as flush as others are.
    The geometry of the blade and its size also play a part.

    Also whether or not you are supporting the work on the work surface or holding it freehand against the supporting platen make a difference.

    I can tell you its a sphincter tightening experience when the blade bites into that belt joint.
    The belt parts and slaps you in the chops,while at the same time the blade whistles past your ear. I was fortunate that I was not injured.

    Other blade makers can freehand edge first into the belt but I choose not to.
