When I've used silver, I've used commercial sterling tubing. For accurate lower class knives, I'd use rolled sheet.

Length and thickness (or thinness, rather) would be the main drawback of a modern kitchen knife. The medieval knives of the Huaswehr/Bauernwehr family are in the 14 inch range and very thick. My blade starts out at over 15 inches and I'll take about an inch for the clip. I assumed I would have to settle for the (Atlanta Cutlery) advertised blade thickness of 1/8 inch for my project, but was pleasantly surprised to find that the blade is 1/4 inch through the tang/grip and tapers down to the tip. I was not thrilled by the heat treatment, however. I gently hacked at a stump and then noticed a 1/8 inch crack running straight back from the edge toward the back of the blade. Fortunately, this was near the spot I wanted to clip the blade so I can live with it. Whaddaya want for $18.95?

Not sure if it helps but I found this photo. It's not exactly medieval (circa 1650 apparently) but it looks like what you are after and was described by the auction house as a german hunting knife.

Hey, that's another nice one to add to my image bank. Thanks! I wonder about the date, though. Looks identical to those of 1500-1550. Did the text say "1650" or "mid-sixteenth century"? Sometimes people get their centuries confused.

Another interesting thread here inspired me to provide an update on the progress (or lack of) on my own knife project.
I haven't spent much time on this, unfortunately, but I've at least finished rough shaping of the blade, roughed out the scales and one shoulder. I can't quite decide which I like better, though--brass shoulder or plain scale (see both sides below). Everything is temporarily held together with wooden pins. Those will be replaced with tubular brass rivets.
I would prefer a curved blade--this one is almost straight and probably not nearly as useful. But it's looking medieval to my eyes.
I'd say this is approximately 1/3 finished at this point. Need the other shoulder, final shaping and finishing of everything, rivets and scabbard. By-knives?

Looking good I would say and I think you could get a bit of curve into the back edge and so mirror it on the front edge and that would just add a hint of curve to break up the straights I think, though as a disclaimer you really have to have it in front of you to properly judge if this would work for the knife.

That's a great idea! I hadn't even thought about filing the back. I'll experiment....
Thanks!

Please excuse my ignorance, but the bolster does not seem to wrap around the tang. So does this bolster consist of two separate plates which are inlaid into the handle in some way? I have ordered Knives and Scabbards, perhaps that will produce some new insights, me being very much into Roman and Frankish seax till know.

For setting tubular rivets I use a large centre punch with a fairly obtuse angle on it, like a roofing punch, held upright in the vice. I just use another small punch, held together with the knife in my left hand, and gently hammer it, swapping sides a few times. This gives a slight flair which can be enlarged with a small ball pein hammer, still resting the underside of the rivet on the large punch, then carefully flattened with the flat side of the hammer with the knife on the anvil. It's a little tricky to balance the knife with your two smaller fingers whilst holding the punch between forefinger and thumb but it's a lot quicker than making a specialised tool like the one that Greg linked to.

It did say "circa 1650". I think it was from Hermann Historica who I'd assume would get it right. Have a look through some of their old auction catalogues, there are some very nice 17th century knives, although I'll admit, this one does appear to be from a little earlier.

A detailed discussion ensued. I won't be soldering my shoulders (which sounds painful anyway), but rather will use epoxy and send the topmost rivet straight through the shoulders. |
Sean, your DIY efforts - many quite fearless - have always been a good source of inspiration to me. Glad I could return just a little of that motivation. That was a really good discussion - I learned a lot.
The epoxy worked, as did both pitch and hide glue, though I prefer the epoxy - you really can't see the adhesive either way if your pieces are tight. If you keep your bolster plates long enough that the first rivet will pass through both the scale and the bolster, it is certainly more secure than without, though with the epoxy, it won't come loose anyway. At some point, I want to attempt to solder mine in place and then go forward with the gripping, but may keep that to a couple of the 16th C pieces I have in mind where the bolsters are more blocky and substantial. Leaded solder is obviously not an option I'm willing to go with, but I'm sure I can find something secure that will set below the tempering temperature of the steel.
Another little trick to think on regarding tubular rivets when shaping your grip - the tubes can develop burrs and can get hot quickly - especially with power-driven abrasives of any sort. I was truing up some pins to the scales after affixing the whole grip together and hurried a bit - embedded a hot burr into the grip. It was in the "extra", fortunately, and ground away in shaping the grip, but it could have wrecked the project.
Darren's method for flaring the rivets is similar to what I did - but I used 3 hands - one to hold the knife, one for the upper setting tool, and one to tap. If I do much more with it, I'll make an upper and lower die for the arbor press.

Something similar - from the early 20th century though...

I've been inspired to essentially copy this project (with some variation of course) as a piece to go with a kit I'm working on, so I thought I'd respond for a bump and maybe an update if Sean feels like it. Every time I get the new Atlanta Cutlery catalog, my brain is flooded with a ton of project ideas. Now I have one with some direction and motivation to boot. So thanks to Sean and everybody who's contributed so far!

I would love to see the result. It seems like today, the expensive swords of the past are all around, but the venerable humble knife of everyday use has been somewhat neglected. I work myself on two knife projects (larger model, chopper-like) - knives are finished and await scabbards.

This one is still sitting on the shelf since I split a grip scale setting the LAST tubular rivet. I was so excited about getting the rivets to work on the first try that I applied too much force. Ordinarily I'd just quickly make another scale and start again but by this stage I had learned so much that I wasn't keen to revisit the project. I think now that if I wanted one of these medieval skinning knives I'd get the "modern" carbon steel version (there was a link around here somewhere) of the traditional design. It'd be easy to make tubular rivets, brass or steel shoulders, scales and a sheath for that and have something much closer to a functional medieval knife. It wouldn't be as thick as some of those that inspired my project, but the curvature would be right, and that's more important to the proper functioning of the knife. I still love these knives, and I still have a Windlass bowie blade to try, too.

Sean - Finished or not, it would be great to see the progress from the last images you shared. Did you ever end up trying to file the spine to get a bit more curve to the blade? Also, which Windlass bowie blade do you have? If you're not planning on finishing this one, would you mind sharing some of your research materials for the project? Thanks.
