Forging A Hatchet by Pasi Hurttila

While Pasi Hurttila may best known for his puukkos and leukus, he recently forged a hatchet for his own use and featured it on his blog, “Life In The North”. I am an admirer of Pasi’s work and asked him if I could do a post about the hatchet and he kindly agreed. Here is the transition of a piece of leaf spring from a truck to a classic hatchet!

Pasi Hurttila:

“On my trips to the woods I always carry a small axe / hatchet with me. I’ve found out that for me a 1kg axe is fairly enough. I’d rather pack a saw too than take a bigger axe. My current user hatchet is the first one I made, about 14 years ago, so I thought I’d make a new one for myself.”

This axe head starts it's life as a piece of truck leaf spring. Cut off with an angle grinder and then annealed.

Then I drill a pivot hole for the eye drift. This is not necessary of course, but helps when punching the eye. Especially when working alone, and without power hammer or press.

Punching the eye. Takes many heatings to get it done.

Blade bit and poll are forged in shape.

Starting to form the blade, for this I wanted some beard, and a bit of thinning behind the bevel to reduce weight.

Corners filed down and shape finished, edge sanded ready for heat treatment.

Edge is hardened in oil, then immediately tempered on glowing coal of the forge. When tempering is finished the whole head is dipped in tar and excess is wiped off.

Then it's time to start with the handle. Shape is drawn and cut off with a jigsaw. This time I used white ash. I still have some planks left from the time I used to make bows. Good material for tool handles.

Rest of the handle work is done with rasp, file, and sandpaper. First the eye part is fitted, leaving last half a centimeter to be hammered in when finally fixing the head.

I like to use cross wedges, so next thing was to saw two slots for them, and whittle the wedges from juniper. Before the handle is finally fixed I sanded the edge of the bit, and finished the handle with coarse sandpaper. Then just fitted the handle in it's place, hammered wedges in with some wood glue, and let it dry. Next day it got some boiled linseed oil for protection, as well for the head itself.

“This axe came out weighing about 800 grams, with a total length of 40cm. Edge is about 7cm. Decent size for my needs.

Most often around the area where I live I use stumps and roots of a fallen pine for a campfire. From these you can pretty easily find fatwood, which lights up easily even in the rain. The downside with them is that they can have some rocks between the roots, so you can easily damage the edge of your axe even when being careful. Stumps with roots won’t always split easily, so I like my axe handle to be relatively thick, especially on the neck, so I can sometimes bend it bit sideways too. On the other hand it can’t be too thick for grabbing it just below the head still.”

The edge needs to be aligned straight with the handle. Decent end knob is a must in a wilderness axe, as you sometimes work with wet hands and tired.

I'm not that strict with bevel/edge geometry of my outdoor axe. Usually I use flat bevel with a secondary, convex works too. This is not a carving axe, so splitting properties are more important than being able to carve nicely.

“I’m not a fan of sharp or pointed lower corner/heel of the bit, so the bearded design gives more obtuse corner without adding weight. Also a flat poll is important for me, for example to drive tent stakes into the ground. The future will show if this axe is to my liking in the woods.”

Update from Pasi:

“I have used it quite a lot since I made it. I reground the bevels to a bit sharper angle, and it’s fine for my use so far.”

  1. W o w ! What a great work! Wonderful hatchet!

  2. What a fantastic write up. The axe is a wonderful piece of work, the lay is spot on. Thank you for sharing your work with us Pasi, I know who to ask if I want to commission an axe!

  3. I like all of Pasi Hurttila’s work, axes, puukkos and Leukus. I would love to visit his shop some day to watch him at work and to see that part of the world.
