During this time, Marking knife holder 2.0 was also reading David's ,arking and followed the process of him making batches and batches of these knives and I heard nothing but great testimonials from them. I grinded and saved a lot! I had 4 things to confirm there was a gap in the market. It looked crap but hey, it was there. Reply 2 years ago. Terms and Conditions. This Swann Markjng craft knife is manufactured in Sheffield England to the same exacting standards as their world famous range of surgical blades an

The lathe had sat idle in my workshop for 4 months while I gathered materials to test the first batch. And I decided to film my first ever attempt at using the metal lathe for Episode 12 of Turning Tuesday. At this point, the knives were complete secret. Barely anyone knew what I was up to! This is where the real challenges arose. I'm pretty sure I exhausted all potential cock-ups possible before finally coming out with a design and a process that works well.

Below are some of my favourite screw ups. There was a split in the rosewood that I didn't see. Suffice to say it didn't like the skew chisel touching it. I forgot to cut the blade slot before attaching the ferrule. Then ended up mashing it anyway I decided to highly polish the ferrule as an experiment, then proceeded to overtighten it in the chuck jaws The slitting saws I use are extremely flexible.

One second I was chamfering the copper, the next second my pants were brown. The shank was too tight in the handle, so I decided to machine it down slightly. Ended up mashing the slot shut. When the araldyte joint failed, causing the ferrule to rotate around the blade holder. You could get a grub screw in that, right? When I forgot to set the depth stop on the drill and blew through the opposite side of the ferrule. One of the many occurrences where the tap snapped while cutting the thread.

This is one of the most annoying! Aradyte rapid didn't work for the wood to metal joint either. These often launched off the lathe. When the slitting saw broke and I decided to mount it on the lathe afterwards as an experiment. It didn't like it. When you're fitting the blade for the final time and it snaps in the slot.

The only slitting saws I could find were available from China. When I got carried away while sanding the handle and ended up shaping the brass ferrule too! A huge problem I faced was breakout within the slot. After adhering the ferrule to the blade holder, every time I drilled and tapped the hole there would be small amounts of metal that would prevent the blade from being fully inserted.

I considered assembling the ferrule and blade holder dry while drilling and tapping the hole, taking it apart, cleaning out the slot, then re-assembling it. But this would almost certainly make aligning the threads difficult. Not to mention the potential of threadlocker leaking into the pre-drilled grub screw hole!

I found that inserting a piece of 0. I usually reserve these ones for myself, friends, and display items if I were to ever set up a stall at an event. After completing the first batch of knives, I have since subcontracted the metal components of the knives out to a small local company. This stops me from having to spend hours slaving over a lathe and milling machine doing repetitive tasks and instead focus on video creation.

However, I still glue, drill, tap, countersink, and chamfer the ferrule myself. As well as turn, finish, and package etc. It's been a real rollercoaster trying to get these things going but the initial feedback has been incredible. I'm seeing lots of happy recipients of their knives all round the globe and I could not be more humbled to see people enjoying them.

April 21, All the way from initial concept, design, prototyping, manufacturing, and fulfilment. This is the story of how my custom marking knives went from an idea into my head, to a tool that people can use and treasure.

The Idea. Answer 2 years ago. This is fantastic. The steps on hobby-shop annealment and hardening are worth the time just by themselves. Question 3 years ago on Step 9. You initially heated the file before shaping it enough to lose its magnetic properties.

You then re-heat it at a later step to again lose its magnetic properties. Did they come back when cooled? Please explain. Answer 3 years ago. Yes, magnetism will return once cooled. Carbon steel loses its magnetic properties around degrees F which is around the temperature you need for annealing and hardening the steel.

I have been hoarding old files for some time now. I pick them up at yard sales, etc. I've wanted to make a knife like this for some time, but I was not sure exactly what I was looking for in a knife, and your knife has given me some inspiration. I like the torch holder you have there, so now I have to make one tool to create another tool. Thanks for posting this up, I really like it. Reply 3 years ago. These are the stones I purchased. I then popped them off the plastic stand and made my own holder for them.

Question 3 years ago on Step This looks great, I may have to give it a go some time. I have a whole load of old files I inherited. Is the steel used for making files particularly well-suited to this, after the heat treatments you describe?
