Declawing a Thule Harpoon Head

I spent a good chunk of the day breaking the Ikaahuk artifact
reproductions.  For the most part they broke the way they were supposed to, so it's all good.  The piece that needed the most damage done to it was the Thule barbed harpoon head from Nelson River.  The original artifact has only one remaining barb, but you can see places on the body of the harpoon head where three other barbs broke off, leaving stumps of various sizes.  The plan from the beginning was to make a fully intact version of the harpoon head, photograph it, and then break it to match the original artifact.  Below are some of the last photos of the complete harpoon head before I cracked the three barbs off (right).

The slots cut on either side of the open socket were there so that some sort of lashing (ie. sinew, leather, baleen) could be used to close the socket so that it could fit onto a harpoon foreshaft. 
The original artifact and this reproduction were both oriented in the antler tine so that the hard outer surface of the antler was on the dorsal surface.  The softer, more porous interior of the antler meant it was easier to carve out the open socket at the base. 
The dorsal surface of the harpoon head.  The small hole in the centre was for the harpoon line.  The larger hole below that is part of the gouged channel for the lashing that closes off the open socket.

So close...

Reproductions (R)
and Artifacts (L)
Every day more and more of the Ikaahuk artifact reproductions are become indistinguishable from the original artifacts.  On each visit now I really need to focus on how I handle the pieces so I don't end up tossing the artifacts in my reproduction box or bagging the reproductions in the artifact bags.  If I absolutely had to, I could probably hand over all the pieces as they are now and be satisfied with the outcome, but I have two more visits scheduled to make last minute adjustments.  I'm mainly working on matching the colour, breakage patterns, and texture of the originals at this point.

The Pre-Dorset Lance Heads and the awls made from old foreshafts are now completely interchangeable between reproductions (bottom) and the orignals (top)

Alberta Spear Points

Reproduction Alberta
Projectile Point
I've returned to knapping a bit more in the workshop this week.  This afternoon I took a stab at a couple Alberta spear points for a set of plains projectile points. I'm satisfied with both of them although I only need one.  One looks better in person and one looks better in photos.  I'll see how the rest of the set turns out before I decide which (if either) will be included in the box.

The Pre-Dorset awl reproduction

Pre-Dorset awl reproduction (top) and artifact
(below), refit with a lance head from the same
site.
The Pre-Dorset awl is the next finished reproduction in the Ikaahuk Archaeology Project set to check off the list.  The reproduction is made from antler and the antiquing includes tea staining, scorching and hand-carved root etching.  This is the artifact that I believe was made from an old foreshaft, so part of the check to determine the accuracy of the reproduction was to match it with the slot on the Pre-Dorset lance head.  I wanted  the spatulate end of the reproduction awl to fit the original lance head as precisely as the artifact awl.  When those two pieces fit together, I felt like I could call the piece finished.  I may continue to tweak the colour and staining over the next few days, but I think this piece is done.

Artifact (left) and reproduction (right)

Other pieces, like this harpoon head are still a couple visits away from being complete.  This one has so many complex angles and symmetries, that its hard to plan too many cuts at once.  Shaving the wrong millimetre at this point could throw off the whole piece.

One down, seven to go...


The offset awl from the Ikaahuk Archaeology Project set of artifact reproductions is now complete.  At this point I have to think twice about which is the artifact (top) and which is the reproduction (bottom) when I have them out on the table together.  Given that the reproduction is made from the same materials and using the same methods as the original, I think for most people it would be very difficult to tell which is the real thing and which is the copy.  The easiest way that I have to tell them apart at the moment is that the wood handle on the reproduction is a little shinier and darker than the artifact because of the oil that I applied to bring out the shine of the iron awl and to help preserve the wood.  As that oil is absorbed by the wood, even that slight difference in colour and texture should vanish.

At this point, other reproductions are a little easier to distinguish from the originals, but once the design goes on to this antler lance head and I antique it, I expect that it will be just as difficult to tell them apart.

Final touch-ups to the Offset Awl

I was putting the final touches on the offset awl today.  I scorched the wood a little with the blowtorch to antique the handle, applied some ochre staining where the awl meets the wood to match some rust on the original artifact and applied a bit of oil to try to match the gloss of the treated iron.  Hopefully it is a good match with the original when I compare them tomorrow.  As the pieces in this set are completed I'll have more time in my workshop to begin new projects.  I have a few projectile points from Western Canada and the Western Arctic to knap next.

The end is in sight...

Offset Awl,
Reproduction above and artifact below
I'm very close to finishing the Ikaahuk artifact reproductions.  I suspect that starting with the next visit I'll be able to finish at least one of the eight reproductions every day.  The first one should be the offset awl.  The shaping is all done and I've fit the awl into the handle.  At this point I just need to scorch the handle with a flame a bit more to antique it and apply some ochre staining to really bring out the rust in a couple places.  If all goes well, it will be done by Tuesday. 

Bola, reproduction on the left
 and artifact on the right
 The bola and the ivory lure should be the next ones done after that.  They are very close to being done, but I may need a couple more visits to work out all of the final contours and to match the holes exactly.  On pieces like this I usually drill small pilot holes and then expand them to match the exact size and location of the holes on the artifact.

The Slate ulu is coming along rapidly.  I had a different one started but it broke, so I had to begin again.  I'm building the reproduction around the large flake scar on the left side of the ulu.  When the shape is complete, I intend to stain it to better approach the dark grey or black stone that the original was made on.  The dark one on the bottom is the artifact, the lighter one on the right is a 1:1 printed pattern and the grey stone on the top is the reproduction in progress.
