Combatchet Proto WIP

[Rick Haney Design]

Another suggestion,Concern regarding lack of material at finger ring area.Due to hard abuse that may be a wink link.Making last minute design decisions.Finger ring not neccesary.IMO.Also add mass where you would want it,The head.

 

[Rick Haney Design]

I realized the head sheath retention strap would have obstructed the use of seat belt cutter.This should work better.

 

[Rick Haney Design]

After removing finger ring,No need for traction notches on the underside of head.

 

[Keith_H]

I still dont see what the small hole is for.

 

[Rick Haney Design]

Keith,It serves as a area the kydex is molded in the hole slightly to index the head to the sheath.Sorta detent.

Simplifiying the sheath without spine & carry box.Now sheathing attachment,I'll have a universal cavity molded in kydex the area of the attachment.I think.The design has come to this configuration.I like the spine idea,I'll make a proto to test anyway

 

[Rick Haney Design]

Lengthened handle 1/2".

 

[Rick Haney Design]

To further simplify the sheath,I opted to remove strapping fixture.
A suggestion was made concerning the comfort of the traction notches on handle,Traction notches on scales only.
Moved hole for head sheath detent.
Moved oxygen wrench slot down slightly.

 

[Rick Haney Design]

After looking at handle length,Lengthened handle & moved handle scales.
Added length in handle should provide better leverage when chopping.

 

[Rick Haney Design]

I modified the spike.Deleted recurve spike,Streamline the amount of attachments.

Tweaked beard edge & sheath

 

[Keith_H]

I am liking the simplifications. Maybe you could have one scale longer than the other so that you can hold it nicely further down and still be able to pry?

 

[Rick Haney Design]

Keith, I might try lengthening the scales.I feel the design is close to being finished.I hope.

 

[Rick Haney Design]

Ok,lengthened handle.
Moved holes & slot.added 1 more hole.
Moved handle serrations.
Beefed up neck area.
Tweaked on the seat belt cutter.
I see the end coming near!Now you can see what goes into the CAD design process,But well worth the work.

 

[Rick Haney Design]

Almost finished,A few more tweaks.

 

[creightonfcb]

Looking lean and MEAN!!! YEA!!


Good call on the handle legnth and beefing up the neck!

[Rick Haney Design]

Frank,Would you recommend cinch straps over snap straps?Cinch straps would secure it tighter for carry or transport.What do you think?

 

[Rick Haney Design]

Needed to draw up 1/4-20 Stainless hex head cap screws to check fit for attachments.

 

[Rick Haney Design]

Down to small changes.

Added 2 locations for possible TekLok at front of head sheath.Chicago screws 1" on center.
Vertical & horizonal oxygen wrench slots on end near pry bar.
Profiled the wire breaker similar to a skeleton key hole.

Waiting on a Molle vest,Get a look at making rig Molle compatible.

 

[creightonfcb]

If you do use cinch straps, use a quick release buckle in order to make it easy to get at if needed...

Molle gear should be in the mail in the next day or two!!

[Rick Haney Design]

Frank,I think a nylon strap with snap should be secure enough.I'm researching strapping materials.Soon as I get my hands on that molle vest,I can make it compatible.Checked with Crucible on S-7,I'm still not sure if I should go up to 3/8"(.375) thick.1/4" or 3/8"?Would 3/8" material be overkill & add unneccesary weight?

 

[Keith_H]

3/8" sounds heavy. Maybe you could waterjet cut the handle to be thinner than the head
