Chip Carving Knives

My Darling Wife decided I needed to learn a new skill for some stuff she wants me to make.
So of course I had to make some new tools.

Chip Cutting Knives

Sadly the wonderful book only had two tools. So I of course made three!!

Then again it did show a compass.

In this case I decided to go cheap, quick and simple. I used pretempered M2 HSS.

I am careful not to over heat even the M2 HSS steel. It is too much work to shape it, and the steel is not at all flexible, but the stuff will seriously hold an edge and work flawlessly for a small knife.

These are really simple to make, I saw a notch in the wood, scrape some carbon deposits off my large tea kettle and then mix some epoxy in with the carbon for the black look. I coat the blade, smear epoxy into the notch, and tap the blade into place. the I fill the notch with epoxy, wait for it to set and then shape the handle.

If you are looking for some good supplies for making basic knives:

I like this one for Screw Posts

Screw Posts look good and are a good backup if the blade comes loose from the glue. I use the unfinished aluminum ones, so I can grind them down and keep the same color. I avoid brass on cooking tools entirely as it may well contain lead.

If you are thinking of tempering your own steel, then O1 is a great intro, and there is almost too much data online telling you how to do it.


This is my source for O1

By the way, if you are going to make blades, get a good belt sander and some good belts.

Poisonous Plants

Nature has made me a hypocrite. And I am a better person for it. We often take stands that on the surface seem right, but with understanding, are fairly weak.

My ideal was to have no toxic plants in my yard and garden. Ignore the fact that that would mean eliminating and fighting a huge number of naturally occurring plants. Ignore the fact that many edible plants are toxic in one stage or another. Ignore a lot of things, such as balance of nature, and It might be possible.

5 poisonous plants

The one on the left is a pepper, the one next to it with the big leaves is tobacco. The one behind and in the middle is an elderberry. The one on the right is a tomato. To the far right, behind the pots is a 4:00.

The tomato, tobacco and pepper are all quite bad for you depending on how you abuse it. All of them can be quite good for you if used correctly and perhaps with moderation. The elderberry is for some a complete cure for arthritis. The 4:00 has the wonderful property of killing grasshoppers. Note that these plants all look pest free and healthy. There is a reason. A bug that has adapted to chew on one of these still won’t survive the rest. I don’t spray or apply pesticides, I plant them.

Here are a few more 4:00 pictures so you can see the other reason for growing them. Just don’t eat them.

A occasional flower in the garden is rarely amiss.

Setting Japanese Chisel Hoops

Chisel comes with the hoop on, but not right. It is on tight, first I need to take it off.

Lots of ways you could take it off, I am using a big hammer, a wooden wedge, and a socket wrench socket a bit smaller than the ring. The socket is held in a vise.

With the chisel on the socket, and the wedge at a 45 degree angle, I can hit the ring and loosen it, without marring the steel or the handle. I had to rotate and pound a few times to get it off.

It came off nicely, and did not roll away because of the socket.

Since the plan is to hammer the wood and compress it for the ring, I had to come up with a neat way to do it. The tape is so I can be sure to pound the wood neatly.

I am using a lighter hammer to pound the handle. The anvil is doing the real shaping. I am only tapering the edge with the hammer. The hammer never gets near the tape.

Now I am using a larger socket wrench socket to set the ring. The socket is large enough for the wood part of the handle to fit inside. A few good taps on the back of the socket with my bigger hammer and the ring will be in place.

The ring is on and a rounded, 45 degree bevel is on the back of the wood. This is a sneaky trick I figured out. Does great, looks better, soaks faster.

Now I soak the end to make it swell up. This also softens the wood so it can be shaped a bit without it splitting as much. Since there is a bevel at the base, more endgrain is exposed to absorb water faster.

The wood is showing damp just above the ring now, so it is wet enough for me to work it.

After pounding the end a bit, the wood is flared, but not split. The chamfer allows this to happen.

Up close you can see the flare, This hoop is not going anywhere.

Here it is mostly done, after making some nice deep chisel marks, the end still looks pretty nice!

One final touch. Don’t know how well this mark will hold up. but it is nice to know the size of the chisel I am reaching for.

Here is a frog!

Now It is ready to be tuned. The chisel that is.

The chisels shown are all Kakuri. They hold a wicked edge, and hone pretty easy. Getting them tuned up did not take a lot, and they do quite well. They seem to keep their prime sharpness about half again as long as well tempered O1, however a hard knot in Osage will consistently put a ding in a 30 degree edge. The osage I used is the cruelest test I could come up with. The knot will dull the O1 quickly but no ding is made.

For pine, these chisels will take end grain off and keep going sharp well after the O1 is dull. So for softer woods, these guys rock, For extreme hard woods, like I often use, these guys don’t hack it. Since I mangle a lot of cedar, and these guys are gems when It comes to cedar, I will be using them quite a bit. Cedar can make the occasional hard as rock knot, so I will be careful.

Getting a few Japanese Chisels has opened my eyes. I used to think that there might be a generally perfect chisel, but now I am not so sure. For an all around chisel, O1 is I think better than this example of a laminate chisel. However for some applications, this beats the O1 hands down.

Mesquite Panel Gauge

The one on the right is the Mesquite Panel Gauge. On the left is the Pecan Marking Gauge.

The pecan guide will not lock onto the smaller mesquite bar, apart from that, the tools are interchangeable. The pencil and blade work with either.

Here is the panel gauge in use. If you look close you can see the line it cuts.

Here is the pecan marking gauge with the pencil in use.

Because the knife sticks out a bit, I have to hold it down with my finger, as I cut, or it will not make a good cut. On the plus side, it is comfortable, stable, and quite controlled. It also ignores grain!!!!

Here it is taken apart. This is the third wedge that I turned for it, the first two were failures. Getting a wedge to consistently grip well can be a challenge.

Here is the panel gauge with the pencil in place. you can see the slot at the bottom of the gauge for the edge of the board.

Here it is lifted slightly to show how the slot at the bottom edge works. Not so stealthy grain gloat included.

Here it is ready to mark, without the edge lifted.

Here are the markers. They can both be used without the gauge! When the knife is set with the curved side toward the fence, the curve tends to push the blade away from the fence. This helps keep a straight line. And it works that way in either direction!
