Buzzkill Posted April 12 Share Posted April 12 Finally got this one done for my brother in law. Blade is 1095 and 15N20, hollow ground on an 8 inch wheel. Hand sanded to 1000 grit after grinding and then etched in coffee. Guard is stainless, and handle slabs are water buffalo horn. Overall length is about 12.5 inches.

Stradawhovious Posted April 18 Share Posted April 18 Here’s #5 for me. 1084, Black G10 with red G10 liners. This pic was just before putting an edge on it. Here’s #5 for me. 1084, Black G10 with red G10 liners. This pic was just before putting an edge on it. Quote Link to post Share on other sites
HondoWalker Posted April 19 Author Share Posted April 19 Didn't make it to the forge this weekend. Finally got a welder. Tried the el cheapo one from HF and it would not weld the angle iron I had set up to learn on. Plus it would not stop feeding wire or turn off until the off switch was flipped. I took it back and traded up for the little green one. It could and did weld the angle iron just fine. I completely suck at welding but those two pieces of steel ain't coming apart. So I pulled out the knife I had set aside and welded threaded rod to the tang. I spent a bunch of time filing down a handle made of alternating black rubber and plexiglass. I found that my weld job sucked and it broke apart. I cleaned the metal up best I could and welded it again. This time I did a much better job. My pieces fell apart so I found a piece of purple leaf plum wood and used that for the handle. It has worked out well and I have spent the better part of two days filing on the pommel. I cut the end off because the pommel was too long. And of course I exposed the hole I'd made and tapped for the threaded rod. I sat there looking at that hole and my first thought was a brass bolt I could fill it with. Had no luck finding one. Was at my desk and spied a piece of brass tube I had bought 20 years ago for launch lugs of high power rockets I used to make. And it perfectly fit the hole. I cut off a small piece of tube and stuck it in the hole. I put 8 pieces of 14 gauge copper wire in the tube and a piece of 8th in brass rod I've had forever. Filled the empty bits with JB Weld. Let it cure and filed it down. The hole is gone. The pommel is 80% filed down. Couple more days and I'll be able to start polishing the blade. Quote Link to post Share on other sites
ThomasPowers Posted April 19 Share Posted April 19 Did you do a proper preheat and slow cool when welding onto the tang? Quote Link to post Share on other sites
HondoWalker Posted April 20 Author Share Posted April 20 I let it cool slowly on it's own. How do you preheat a flux core welder steel? Propane torch? The first weld on it had a small bit attached together. The second one had it all melted together. It hasn't budged and I'm almost to the point of polishing it.

Chad J. Posted April 20 Share Posted April 20 I had a blade break when I dropped it after heat treat and before tempering. I welded it up, cycled it several times and when I was going to heat treat it again I noticed an uneven heat across a straight line. It had cracked again right along my weld. Would that had happened if I had preheated? Not sure but I've done it every time since. Quote Link to post Share on other sites
Frazer Posted April 20 Share Posted April 20 If the actual blade itself broke, welding it back together isn't going to help unless you have some fancy tool steel filler. A bead unhardenable material in there will lead to warping or cracking along the weld, not to mention the edge in that spot will be compromised,. If the crack formed before quenching (after welding), then yes, preheating and slow cooling would have probably mitigated some of the risk of cracking. If you have ever welded a frame together, you know that as the bead cools it pulls the two pieces together with a significant amount of force. When you're welding high carbon steels, you are heating a small area above critical temperature, which rapidly cools due to contact with the surrounding material and hardens. At the same time, the weld bead is pulling in on the surrounding area as it cools. This can lead to cracks. Preheating the whole area to be welded and allowing it to cool slowly lowers the risk of these cracks forming. Quote Link to post Share on other sites
ThomasPowers Posted April 20 Share Posted April 20 Contact quenching is an issue when welding high carbon steels. Preheating can help avoid the formation of cracks in the HAZ from untempered martensite. This is why the good anvil repair methods always include preheating the anvil. (Heating a 400# anvil to 350 degF takes a while and a lot of propane! I know; it was my anvil we used an optical pyrometer to check the temp and propane weed burners for the BTUs.) Now if you have to ask folks how to heat steel up; perhaps blacksmithing is not a good match for you! A lot of folks I know use two firebricks to make an angle and a torch for small pieces; up through using a pile of charcoal briquettes or the weed burners. Steel won't know it gets hot in the proper pre heat ranges. Quote Link to post Share on other sites
Will Robisch Posted April 22 Share Posted April 22 I made this out of a rail road spike, turns out it is not the best steel. Quote Link to post Share on other sites
JPoor Posted April 22 Share Posted April 22 Railroad spikes aren’t very hard. They are fun to make though. Quote Link to post Share on other sites
Irondragon ForgeClay Works Posted April 22 Share Posted April 22 I used to make throwing leaf blade knives out of them. They worked very well for that and they sold like hot cakes when we used to set up a booth at events. Quote Link to post Share on other sites
Frosty Posted April 22 Share Posted April 22 Actually RR spikes ARE the best steel for . . . holding rail down. The steel is specifically made to NOT get hard, the last thing you want is the spikes keeping they rails in place (holding gauge) to work harden and snap rather than flex every single time a train wheel rolls over it. If you've watched some of the youtube videos where the "smith" demonstrates a RR spike knife will hold an edge. Watch closely, every cut is a different knife or there's sufficient break in continuity for them to have sharpened it. Frosty The Lucky. Quote Link to post Share on other sites
Irondragon ForgeClay Works Posted April 22 Share Posted April 22 That's why they made good throwing knives. They were tough as nails and only had to hold the point. Quote Link to post Share on other sites
templehound Posted April 22 Share Posted April 22 Take the opportunity to practice small details whenever the shape of the blade allows. O7 combined with copper and Burma ironwood. Blade length measures 4 inches. Tang is riveted on the butt. Cheers Quote Link to post Share on other sites

HondoWalker Posted April 23 Author Share Posted April 23 Here's the one I ground out of Lowe's bar steel. It's how my dad made them. And compared to forging it is super simple to do. How did he get $350 per knife back in 1984? According to Ebay custom made knives go from $20 to $75. Have to find some super glue before I can finish the one with the pin and a welded tang.

JHCC Posted April 23 Share Posted April 23 I wouldn't trust eBay as a source for information about the custom knife market; true handmade knives from reputable makers go from the hundreds to the thousands of dollars. How are you heat-treating the blade? My understanding is that the steel from Lowe's is lowe-carbon. Quote Link to post Share on other sites
HondoWalker Posted April 25 Author Share Posted April 25 And here's the one that I welded the tang and placed a pin in the pommel. I concentrated on those two aspects so I neglected others. Plus it's the knife a split my pinky finger working on. Should have got stitches. The wound is healed but it still hurts to move it.The handle is purple leaf plum. I keep finding bits of it and using them. Still getting better at the knifemaking. Not as good as some of the knives posted in this thread. You guys put me to shame. Really good knives.

Ed Steinkirchner Posted May 6 Share Posted May 6 Thought I Might as well kick in on this thread, lot of nice stuff thus far! Blade is simple hc steel (1085 I believe), guard and pommel are brass, handle ebony, sheath is leather with bronze and copper fittings Quote Link to post Share on other sites
HondoWalker Posted May 15 Author Share Posted May 15 This latest one is made from a can opener handle. It's the first one I made using my new 72x2 belt grinder. Saved me hours and hours of filing and using my weak 4x38 belt grinder. I forged it on a Tuesday and had it finished the following Friday. Usually takes 2 weeks. Only gashed my thumb's knuckle once.

Scalebar Posted May 17 Share Posted May 17 My second knife and seventh thing I've made from ferrous metal. Just a basic kitchen knife. This was my old plaster file - lost in a leaky shed for years and well on it's way to becoming a concretion. Managed to get down to just over a mm on the edge by hammer, it's ever so slightly serrated. The wood is Leyland cypress - I think I have a new favourite, it's easy to work, comes out a treat with shellac and thanks to jerks illegally dumping, there's plenty sat there ready seasoned. Bolster's horn. Quote Link to post Share on other sites
Frosty Posted May 17 Share Posted May 17 Close ups with oblique lighting please! I can't see it well enough from this far away. The wood looks very nice from here. Frosty The Lucky. Quote Link to post Share on other sites
