flint knapping

glass bottle recycling.

Hello there. It’s time for another update.

It’s my latest space age material. Recycling to the max, if you will.

So a month or so back I decided to see if I could melt bottles into knappable slabs in my kiln. First try, right off the bat I get it right. When you melt the bottles at cone 05 you avoid any complications with crystals forming from the kiln wash and you get a perfect melt. Because of how thin the glass slabs are, the annealing happens over night. Make sure the glass is cool to the touch before you decide to take them out into the harsh air.

Here’s the first point that I got out of the bottle glass slab.

That point is worth a heck of a lot more than it would have been if I had just got the deposit back on the bottle. If you’re interested in adding this, or any of my other work into your collection you can check out my online store by clicking the link below:

A tomahawk gift

Hello there, thanks for dropping by, today I’ll be filling you in on some of the things that I’ve been up to this summer.

First on the list is this tomahawk that I made as a birthday present for my good friend Matthiew Dyck. Here’s his website: http://matthewdyck.com/blog/

The hawk head is made out of a really nice piece of midnight lace obsidian from the Glass buttes Oregon. The handle is a seasoned old piece of lilac that I collected from a demolition site. It breaks my heart to kill beautiful old plants, but I’d rather put them to use than have them trucked off to a landfill. I made the jade inlay from a scrap of jade that I picked up off the ground at the maple ridge rock club.  If I remember correctly I stuck the hawk head into the handle with pine pitch glue.

My tomahawks are fully functional as chopping tools, for throwing, they would be able to wistand being thrown into soft targets such as straw-bails, foam-board or a deer but I have had some trouble with the obsidian cracking when the hawk is thrown into wooden targets.

If anyone is interested in commissioning a hawk drop me a line and we can work something out. For a tomahawk like this I would want somewhere in the neighborhood of 400$. My pricing depends on the wood for the handle, the material for the hawk-head and the overall size and quality of the finished piece.  If you are interested in a hand knapped, throwing tomahawk I can make the blade out of some tough rock that will take a real beating. My email is harleyslade@hotmail.com or you can reach me through the comments here.

Thanks for stopping by, and I look forward to doing business with you.

The last post of march..

Thanks for all of the support everyone! It’s hard to believe I made it through the month. Special thanks to my girlfriend for proof reading and editing almost all of my writing. It makes a huge difference and I can tell the ones you missed c:

My plan for the future is to write an entry every Sunday, Wednesday and Friday for the next few months, so be sure to tune in and see what I’m up to.


Last Wednesday I made a Humboldt spear point for my flintknapping Youtube channel (link will be here when it’s finished uploading). After I was finished I made a cedar frame out of planks that I split off of our old chopping block. I stained the wood with charcoal and beeswax and hand carved all of the joins. I’m going to use my dad’s radial arm saw soon so that I can get better fits in the future, but until then I’ll have to cope with my little draw-knife.

The spear point is glued in with hot glue and fastened with homemade stinging nettle cordage.

I hope you like it!

White petrified wood point

I bought this piece of rock at the maple ridge rock club. It’s a great slab of some even better material. I think it may be opalised wood from Nevada. It’s the only place that I’ve ever seen a stone like that come from. If I had to guess I would say it came from McDermit nevada.

This one’s for sale here, if you’re interested: it’s 35 bucks

TV glass clovis

The old CRT televisions make for an awesome source of knappable glass. There is phosphorous powder on the inside of the tubes that pose a health risk but there aren’t any immediate negative effects except that cuts don’t heal as quickly as they normally do.

There is a certain irony about making a stone age tool out of a modern technological wonder, that I can’t get enough of.

Flintknapping Obsidian.

The formation of obsidian is a highly debated subject. The main issue lacking consensus is the composition of the lava. The average flintknapper believes that obsidian was formed from lava that was over 80 percent “silica” (SiO3) cooling rapidly on the surface. The rate of cooling is correct but geologists say that the lava would have had to cool in an ocean, not the surface, in order for the lava to cool quickly enough. Geologists also say that the composition of Obsidian is chemically identical to that of granite and rhyolite, crystals formed from slow cooling deep within the earth.

This is not the only theory on chemical composition that I have heard, though. Some say that basalt has the same composition as obsidian and granite. We know basalt is a primarily mafic (melted oceanic crust) lava, while granite is formed from felsic (melted continental crust) lava. These parallel contradictory theories, both taught in schools and readily available on the internet, are the root of the confusion we the flintknappers face.

Here’s one of my theories. Obsidian was molten rock… and came up to the surface in a way similar to basalt. The lava had a relatively low silica content (less than 50%) since lavas that have high silica content are much more volatile and tend to make extremely explosive volcanoes. Lava flowed out of the shield volcano underwater, cooling the stone almost instantly without allowing any air to enter the obsidian.

The composition of the lava doesn’t matter because the cooling action would be the same as the process for slag glass. Slag glass formed from the rapid cooling of a molten random rock mixture. If anything molten cools fast enough, you can get it to form a conchiodial fracture. This can be seen whenever a cheaply made cast iron pot is dropped, since they will occasionally chip.

However the stuff is formed, there’s one thing we can all agree on: you can make some awesome stone tools out of it!

a pair of peanut butter points

Howdy everyone. Today I have a couple points made out of my homemade stone called princeton peanutbutter.

Princeton peanut butter was originally an ashflow-cherty-tuff which in essence is basically a pyroclastic flow composed mainly of fine ash particles. The flow, I believe (due to partial grading on the top of the deposit), had a river flowing over it before it was lithified. The bed of ash and plant debris was berried for only a short period of time, with very little heat and pressure, before it was brought back to the surface (perhaps due to isostatic rebound from the receding ice ages.)

The composition of the ash-flow must have been rich in silica and other clay minerals because when I put it in my pottery kiln up to cone 3 the stone vitrifies and changes colour.

It’s my own little homemade stone, I love working it and it makes some of the most interesting points.


This is the first point that i made out of the superheated stone. I  made it the same day after the piece came out of the kiln.

Here’s a whole bunch of paleoplanet threads if you’re interested in reading more on the subject. Please excuse the bad grammar in these paleoplanet threads. haha





and one post form my old teenagecaveman blog



Thanks for dropping by!  my appologies for a late blog post today.. I’ve been swamped with school work for the past two weeks.

Tune in tomorrow for a sweet article on Obsidian.

onondaga chert

Well this was the first point that I made as a twenty year old. I don’t have time to upload photos right now but here’s the link to my paleoplanet thread.


Here’s a couple of photos of the point.

Take care.

glass gunther

This is another point from a video series. I made it last Wednesday. It was a request from one of my viewers.

click here for the video series,

I think it turned out alright! let me know what you think.  Oh, this one’s for sale on my flintknappers.com store if you’re interested. here’s the link

I hope you like this one. It was fun to make.

Tune in tomorrow to see another cool point.

the last point as the teenagecaveman

Well it turns out that the last point I filmed myself making on my youtube channel was also the last point that I made as a teenager.

click here for a link to the video series..

It’s a European flint Clovis attempt, the material sure is pretty..  I wish the flutes went a  little bit further instead of not going at all…  It’s an un-fluted Clovis! haha

see you tomorrow!
