Been working on some prototypes for some combat knives of late.
These are an off shoot of that work.
My goal was to reduce a knife to the very smallest and simplest design while not loosing the function.
I have always liked ring knives but never saw a design that wouldn't pivot around and cut your fingers, so I added a spur to prevent that. An unexpected benefit was much better control and a surprisingly useful little design.
I call them Cat's Claws because they are easy to "velvet" until needed. Crafted from Aldo's 1/8" 15N20 and differentially hardened, these blades are shaving sharp.

Some pieces I did recently for Privateer Armoury
First is a blunt training messer:
Length:33 1/2"
Blade: 25 1/2" 1/4" thick at guard with parabolic distal tapers in both directions.
Weight: 1lb. 15oz.
Pivot: at tip
PoB: 3 1/2"
CoP: 16"
SN:-2"

 

 Next is a Dao/Cutlass
1/4" thick blade. Heavy but handy and wicked sharp.

And another training messer,
1/16" thick blade.

PoB: 2 3/4"

Pivot point: at tip

Primary Node:16"

Secondary Node:-2"

Weight: 1lb 8oz.

Blade:15N20 25"

Grip:Bloodwood with steel pins 7 1/4" (from guard to pommel)

Here is a sample of what I've been up to lately.

Two Users, first of a new process

Here are the first two knives (besides the prototypes that where tested) for a new line of affordable user knives that I am working on.
They have Aldo 1095 edge quenched blades and hard wood handles.

Indian Rosewood with Copper rivets

Kingwood with steel pins and a welded steel guard.

Here is my first Sgian dubh, If was made to the customer's specs., Flame darkened maple grip, carved with a celtic hound, 1095 3/4 edged blade with file work and a Japanese differential quench showing the hamon, and silver alloy mounts.

Metallic Glass Tactical

This is my first "tactical" knife.  It was quite a challange working with the metallic glass as it has to be kept cold during the grinding and the dust is toxic. I had to build a containment barrier in my shop and wet grind  with flood cooling, and all the hand work had to be done wet or underwater. the properties of the material are interesting according to inventor it is self sharpening, non-magnetic, highly corrosion resistant (except for clorine based compounds), and harder than many steels. It is quite different from steel in many ways sharpening stands out (as I just finished that) as it doesn't need to be stropped, in fact the structure is such that a few passes on a 320gt diamond stone will but a nice edge on it that gets better with a bit of cutting. I did a limited amount of test cutting and was impressed with the material.

The knife is 6" overall with a blade made of a metallic glass (zirconium, beryillium, etc) that is technically a liquid.
The grips are Carbon Fiber and are held in place by Titanium pins.

 I really enjoied working with the Titanium and the carbon fiber, although the carbon fiber requires quite a bit of planning to avoid making a complete mess of the shop (and your lungs, hands, etc.).
I am planning on working with both of the handle materials again in the future.

Here is my first Fighter (for a military customer).
