The "Ask Nathan a Question" Thread

[WValtakis]

I think there's confusion here...the boot daggers are NOT integral daggers.

See, they got a bargain!

If it takes $6000 to turn a profit on the dagger, I shudder to think what it would take for the KOD or even the potato knife.

Integral Dagger:

^ those are a bear

 

[Big DJ]

Those are truly a work of art.

I couldn’t swing 6k for that at this point in my life but I would get a good part of the way there. Really incredible intersection of design and craftsmanship.

Nathan the Machinist how are the scales attached? Hidden pins and epoxy?

Here, this is from a thread a few years back when I made the dagger



This was a special project I've been working on here and there for a while now that I finished in time to show at Blade this year. I've posted a few pictures on IG but, being a regular here, I thought you folks might want to see it too.

It's a 14" integral made of CPM 3V at HRC 60.5 with the Delta heat treat protocol, so it is a "real" completely functional large dagger, not an "art knife". It's 14 5/8" from tip to guard, 20 3/4" total length, 3 1/2" across the guard and about 15/16" at its thickest in the pommel. It is .350" (a hair under 3/8") at the ricasso.

It started out a little over 24 pounds and ended up a little over 24 ounces

I used deep hollow grinds in the blade and varied the cross section of the fuller from 3/8" diameter to 1/8" diameter as it went along the length of the blade to maintain the depth of the fuller in order to remove unnecessary weight from the blade...

...and being an integral one can't really put material back on so I used engineering software before I started cutting it to size the weighted pommel to put the center of gravity just ahead of the guard.

So despite being pretty stout (almost 3/8" at the ricasso)...

...it's 24 ounces, not at all heavy for its size.


I did a variation of the "two tangs" thing again that I've done on previous work.

I like this kind of tang both aesthetically and functionally. It's a cool look that you don't see much, and despite tapering down pretty thin it's robust because it has a pretty good cross section of steel in both planes.

I twist the grinds in a shallow helix out into the blade and then twist back steep again as it approaches the tip.

This twisting of the grinds allows me to control the thickness of the blade along its length rather than simply letting it become the natural result of the intersection of the grinds and fuller as the width of the blade narrows. The goal being a strong robust point that can penetrate hard objects with a lot of force with minimal risk of breaking.

^ left to their own, the intersection of hollow grinds creates a weak hollow center ridge at the point. This was forced into a stout convex center section. Historically, weapons were commonly done this way, but I don't see it done this way very often today.

My goal with this dagger was not a historical reproduction of a particular blade of a particular era. Instead I was thinking about a bladed weapon as a killing tool in a modern context. And, not a modern "tactical" dagger, but a classic weapon made in a modern manner. It's difficult to really convey the feel of a knife but the metal and scales are not polished into something shiny and slippery but left textured. The handle is sized for a large hand and shaped to sit across the hand at an angle to project reach. It isn't heavy or clunky (unnecessary weight was removed from the center of the handle and the center of the blade), though it is weighted on the ends as these were historically done to resist deflection from an impact, and as a result it doesn't flick around lightly but wants to stab in a straight line.

I'll post some work in process pictures next...

Wow!

 

[Big DJ]

It truly is a thing of beauty.

 

[Xr6x]

Truly a blade of perfection in workmanship as well as beauty

Nathan, I have a pretty good idea as to where that 6K figure could have come from: perhaps you just extrapolated from the last project + added inertia on your part to start on another I.D project(s) with all the additional work load / expansions which you have taken on since. however, considering that last Internal Dagger was both unique and a one-off custom project, maybe one day, someday, you will find the motivation to do a limited and exclusive run of the 10" I.Ds.

TBT, I will balk at 6K but I will gladly add my name to a list for the 10" version in D3V if the numbers become feasible to you at all in the 3K+ region (give or take). I think that you will find up to 20 like-minded folks, perhaps more if you get multiple orders, right here in your sub to get this project off the ground. I will only speak for myself, but I will gladly pay fully upfront and then wait 2-3 years for such project to get to completion. Do not dismiss a trial balloon on this one so summarily

You shouldn’t do another integral dagger for less than $9000 imo. Don’t undervalue your time...it’s all we really have to sell in this world

I promise that I won't be!

exceptional craftsmanship sir!

 

[bluemax_1]

Soooo... you could scale that up 2x the size and make an integral CPK Bastard Sword?

Based on my frustrating experiences trying to make a fuller and a distal taper on a mill at work, I declare this not only a masterpiece whatever the method of construction, but also a master class in machining. Congrats!
