    Well i have this one ground out and almost ready for HT. Stock is just a hair under 5/16, and blade is 2 inches high with a full flat grind. This one is 15 overall with a 10 inch blade and 5 inch handle and man, did this ever take a long time to bevel. The scales will attach with three lanyard tubes to allow multiple tie up positions so that the blade cant get away while chopping. Not sure what the scales will be yet, but i am thinking about possibly trying some horse stall mat on them. This knife is just an experiment, its made to do specific things well, and other things not at all. It is supposed to chop hanging rope, chop 2x4s, take down trees, slice waterbottles and such. It has no tip, and will not be any good at all for skinning, filleting, or any type of fine detail work.

    Sorry i guess i forgot some details. The steel on this one is 5160. It will loose a bit of weight after HT because it will get taken to a near zero grind, and i still need to drill a few more tang holes, just to help with epoxy bonding. Current weight on my cheap digital fish scale puts it at 1.3 lbs. This could be right but i think the scale usually shows low, since i know some fish i have caught were bigger than what it showed lol ;)

    Yes its a bit crazy and by far the largest knife i have ever done. I have a bubble jig from Fred Rowe and it really helped with getting a consistent FFG on a blade of this size. Like i said, its not a do all knife, and really, its not even a do much knife. It will be strictly a heavy duty chopper, and something to mess around with. Hopefully if some of this snow ever melts it will get a good workout clearing some brush at my cabin, and clearing shooting lanes for our archery clubs annual Outdoor 3D shoot. Its not even heat treated but i have had two offers to buy it already haha. If it turns out good I may make more, but I'm pretty sure this beast will be a keeper for myself. I hope to get this and a few others out the door this week to HT, but that part kills me. Every time i pay shipping and HT fees I cant help but think that its just more cash that should have went to the kiln fund. So far all my knives that have sold have been commissioned before they were started, but I would love to find a way to list and sell ones that I make that are not for orders.

    Grayzer, I have a Facebook page strictly for my knives it's free advertising and I can barely keep up with orders but if you do something like that it's an easy free way to list? Just a thought?

    Sounds like a great plan Steve, I guess I may have to learn to use Facebook. I think I might be the only 27 year old person in Canada that doesn't already use Facebook. Rob, I will have to verify the date of the 3D since I missed our last meeting playing hockey

    Wow man! That's awesome! I can't wait to see it in action :)

    I also have a Facebook business page for my knife making. It only has 40 likes but I have already generated several sales from it. It's worth a shot and its free. Just google JSK knives and you should find it if you want to check it out.

    Sorry to drag this thread back up but I have to say that this knife has really given me a lot of respect for 5160. I have been very impressed by the edge holding and toughness. I have literally beat this knife up, and it just takes it and asks for more. I have chopped, batonned, and hammered it cross grain into logs. I drove the first three inches into a stump and flexed it as hard as possible short of putting a pipe on it for more leverage, and it would not take a set or break. The only thing that had cause any edge damage was when I smacked a broken off bolt hidden inside a 6x6 I was chopping up. Just today I used it to quickly clear some low hanging and fallen trees to get my work truck down an old bush trail. The guy who showed up later wouldn't believe that all those 1.5 inch trees that were sliced off in one cut could have been done by a knife I made. I know I will definitely be using 5160 in my large hard use knives again.

    5160 is one of my favorite steels. It sure can take a pounding and come back for more

    Sure thing Rob. Preparation is very important, so I always make sure to wrap it in cardboard. After that I fire up the forge to preheat, figure out what end hardness I would like, write it on the cardboard, and ship it to Rob at knifemaker.ca. Then once the forge is heated up I put some steel in and beat it into another knife shape while rob does the other heat treat lol. In all seriousness I have heard 5160 is doable at home in a forge but can be hit or miss so I just sent it out.

    Lol...that's awesome ;). Hey Rob there is a mini blacksmith series called Man At Arms you can watch on YouTube. He uses almost exclusively 5160 I think all he does is heat and hd at 1500F, quench in oil and temper at 600F. But all in all pretty neat series.
