Just to repeat this bit from the video description, I used O1 Tool steel, and tempered @ 480F (250C) for 30 mins - to get an easily sharpened edge. My last blade video with this (same) steel shows the packaging label detailing the exact tempering temperatures and times. ua-cam.com/video/SkII_ZpOwh0/v-deo.html Those blades were tempered @ 390F (200c) for 10 mins and it turned out really hard and durable (almost too hard) I made those blades in 2020 and it took a lot of work sharpening them, but I have never had to resharpen. One last tip, if you are going to use your oven, quench in cooking oil (not something like old motor oil) so you don’t leave a horrible smell in the oven. Happy wife = happy life
they came out really nice Matt, good job. Maybe a good thing that the first blank exploded on the lathe, as the carved shape looks to be more comfortable in the hand too!
You've done a cracking job of these mate! I was happy to see you get the lathe going, even though the timber was brittle! saying that though the hand carved handle with the rasp looks great! cheers
Nice project, I bought mine from pinewood forge, I am short on time wanted to get busy kolrosing. If I get some slack I’ll try to build one, also a guy once told me to try using two live centers on the lathe, might stop the frag factor.
every time I watch knife making, I am pulled into it. I think for a marking knife, I would make one side of the blade flat, so that it can follow the reference walls (oh OK I've seen your marking knife video, where you did make one side of the blade flat, now I learned what Kolrosing knife meant). PS Congrats on 780 subscribers (as of Sept 1 2022), you are very close to 1000!
Thanks, you are over half way now too. Soon to to hit that critical mass. :) Re that video on the marking knife with this same O1 tool steel. I think it ended up harder using the BBQ forge method for some reason. Maybe soaked up the heat more? I use it all the time and have never needed to resharpen, so the hardening really works. Of yeah, same steel as that little plane i sent you. I am going to do another kolrosing knife vid soon, a collaboration with a guy in US who is going to make the handle part.
@@Saw-IT I don't mind to make it harder, and keep the edge for a longer time. I am willing to spend more time sharpening it. my commercial marking knife is so soft, it is almost useless. I need to make one soon.
@@Saw-IT yes files are extremely hard. I was thinking of using HSS steel stock for the metal lathe tools, and learn how to harden it to HRC 65 by watching Japanese blacksmith
This was a great video! I made a marking knife the other day out of a old thickness planer blade . And like a bone head i didnt aneal the blade and it was entirely too hard to drill the steel to install brass pins for the handle scales lol but i am planning on taking another crack at it . But i definitely want to order some tool steel so i have a definite recipe for heat treatment instead of mystery metal lol
Thanks heaps and hey, I saw your marking knife vid and i really liked that slim handle shape. It is a great idea and totally my philosophy to reuse old stuff like planer blades. But you are right, having a known material that is super easy to work and then harden later is worth it.
Hi! I was so excited to see this. I have just started carving and wanted to learn kolrosing. Have tried a couple of knives but thought a proper kolrosing knife would be worthwhile. I don’t have the equipment to make one but do you make them for sale? I live in Australia and would love to buy Australian made🙏 Thank you 😊
Hello Toni, I only make things for home family, friends or just the sake of making a video. I am not interested in sales. If you live on the Sunshine Coast, I could knock one up with you in the workshop, making a video of that and then give it away? I will need to check but i am pretty sure i have a spare blade.
@@Saw-IT wow! Sounds amazing- I live in Maleny!! Currently I am in Ipswich caring for my dad who is dying. Doing carving on the verandah of his house has been a great source of comfort for me and so have been making spoons - comfort birds etc and giving them away. I am very much a novice but am so grateful for the beautiful wood I am holding and working with. What you do- I am very excited you do. If you would consider making me one- I would feel it would be very very special. More special than Australian made- local made!! I would happily gift you something I make too🙏😊
Hi! I have come back home to Maleny for a week respite. I just made another spoon and thought again about kolrosing it. Yes thought of you too. I do not want to bother you but wanted to ask you just to check now I am home if you might like to make one for me. And yes obviously I am ok if you can't.🙂 Thank you 🙏
@@tonilynch7872 sorry i don't have time to make another, I like the video idea of making it "with" you for you take it home, people dig that sort of thing because it has a human factor. But I am struggling with getting time in the shop to make videos and have to be selective with the projects sorry. One of my next projects are two spoon carving axe blocks for a friend. The click bait interest factor there is that I am making two different styles. like this video where i make two different style knives.
@@Saw-IT Thanks for letting me know. I will look forward to seeing your axe blocks 🙂 I am always checking out axing blocks on UA-cam to see how I can modify mine. I just picked up a new stump from a neighbour up the road to make a new axing block and made him a wooden butter knife (yes I did some kolrosing on it with the carving knife I have,!) He was interested in what I did and was hoping to interest his son in it. So yes- there is interest out here! Good luck with your next videos! I am keen to see them.
Hi JK, I purposely left that detail off sorry because it is not an exact science and perhaps there are different O1 tool steels.

My last blade video with this (same) steel shows the manufacturer’s packaging label detailing the exact tempering temp and for how long. ua-cam.com/video/SkII_ZpOwh0/v-deo.html I did 390F (200c) for 10 mins and it was really hard and durable (almost too hard) I made those blades in 2020 and it took a lot of work sharpening them, but I have never had to resharpen.

Yeah, thanks, good idea, I will put it in the description and a pinned comment. Oh, I also used a MAPP gas torch which is a little hotter than a standard propane bottle.
Thanks heaps Drew, Ok i was thinking of having another go at turning that cypress into a handle for another knife, is that the sort of thing you would like? or perhaps we do a collaboration where where we make half each? Postage to and from Australia could make it expensive though.

Thanks Mario, for sure! And it was really satisfying just letting the handles take their best shape organically.
Great video nice and easy to follow. Very good for me being a beginner.
That is cool and I am really glad you let me know. Thanks.
You've done a cracking job of these mate! I was happy to see you get the lathe going, even though the timber was brittle! saying that though the hand carved handle with the rasp looks great! cheers
Thanks Sam. I might actually turn some of that wood as a challenge. Rasps and files are real handy tools for roughing out handles.
Awesome job! looking to make some myself and get into this!
Go for it!

Hey Thanks Rollo I will try that and those knives from Pinewood forge are beautiful ready for work.
Great video! Thank you! Cheers from Canada 👍 new Sub 😊

@@TigerCarpenter you could convert a file, as long as you keep it cool while sharpening?
@@Saw-IT yes files are extremely hard.

@@TigerCarpenter that sounds like the pro way to do it.

At what temperature and for how long was the blade in the oven for?

Yeah, thanks, good idea, I will put it in the description and a pinned comment. Oh, I also used a MAPP gas torch which is a little hotter than a standard propane bottle.
Argh so this is why you always need to make two... so you can use one to engrave the other 😅😅
That was the plan haha. then gave the camphor laurel one away. BTW the plane should have been delivered by now. 😃
@@Saw-IT I'll visit my parcel locker tonight 😊
Nicely done! We need to do a trade!1
Thanks heaps Drew, Ok i was thinking of having another go at turning that cypress into a handle for another knife, is that the sort of thing you would like? or perhaps we do a collaboration where where we make half each? Postage to and from Australia could make it expensive though.
@@Saw-IT I would seriously love one of those knives, I’m just trying to think what we could trade. Also some sort of collaboration would be awesome!
@@bill40bates tell you what. Email me your postal address (it is in my about page ) and I will send it to you one as a present. No trade necessary.
@@Saw-IT Matthew, you are amazing! I’ll come up with something to send back!
Oops. I checked for the email and didn’t see it.
@@bill40bates it is there under about>details, but I found your email and sent you one.
