Review : Klecker KLAX Lumberjack axe

I finally received my KLAX Kickstarter axe-head in the mail, after languishing I development hell for a while, getting the engineering tweeked. The KLAX is a multi-tool built into the head of an ax.  It allows you to attach the ax head to a handle quickly in the field.  It uses the nested clamping system shown here.   The clamps rotate out from the handle for use. The multifunction options are what really drew to me to the KLAX, and I was very curious to see how the fold-away stow-away option worked.

The Lumberjack is the Klecker high-end stainless steel model with the most features. The first three models are all made from heat treated SUS420J2 stainless steel which is perfectly balanced for keeping an edge and maintaining strength. Klecker do offer a Gucci, titanium version of the Lumberjack model as well, but I wanted to stick to steel for a hatchet head.

The Lumberjack features, as well as a fairly broad axe head, an Ulu knife blade, a hammer head,
cutting/gut hook, a set of skeletonized hex wrench set (19mm, 15mm, 13mm, 12mm, 10mm, 8mm), as well as a 1/4” hex bit driver socket, an inch ruler along the hammer-head, a lanyard hole and an inset wire-gate carabiner (which can be used to clip the sheathed axe-head to the outside of a pack) and a bottle-opener (mate!), all coupled with their Patent Pending clamping system.

The hardness of the axe is around 48-52 HRc. The purpose of this hardness level is to give it the strength it needs to work as an axe but keep it from being too hard. Too hard, and you risk chipping and shattering. 

The clamps are centered on a 1/4"-28 threaded bolt shaft which requires over 450kg (1000lbs) of load to shear it, so you're talking a fair amount of chopping to risk that.

The "front" clamp is threaded and rides along the threaded section of the bolt shaft. It is activated from its stowed position by rotating the nut at the back. When the head is inserted into the handle, it is screwed down and clamped in place by turning the knob the other way.

The "rear" clamp rotates out of the handle and is spring loaded to drop into a notch specially shaped to hold it in place. Once the clamp is tightened, it cannot be turned, bent, or otherwise moved until you loosen the system with the nut.

The KLAX is cut from a 5/16" thick SUS420J2 piece of steel plate with a water jet and then machined to add the side bevels, the caribiner pocket and the cutting edges on axe blade.

The clamps themselves are also 5/16" thick and are extremely rugged as well. Like the head, the clamps are heat treated in order to increase their strength considerably.

The clamps are working correctly when they are seated in the handle notches and have been fully "seated".

To seat the clamps into the handle,   its just a matter of tightening the nut, hitting the axe a few times (blade or hammer, it doesn't matter,) the first few times you use it, and tighten the clamps as tight as you can by hand.

Repeating the process, until the head is secure and then it is ready to go. Given the transitory nature of the attachment, it makes good sense to  to check the head periodically and re-tighten as needed.

Kleker suggest that typically it will no longer loosen after about five minutes of use, but make sure to check it anyway.

I've had some fun chopping wood and things with it thus far, and it certainly seems like a great back-up axe to stow in the outside pockets of a hiking pack, and even without the custom fitted hardwood handle, taking the Lumberjack into the field allows you to use a locally sourced piece of wood,trimmed and split with the ulu blade, and then slid over the head. The clamps just need the roughest of notches for the clamps to seat into, and the self-compressing nature of the clamps will pinch down a split log to give an extra tight grip.

I haven't had a chance to try this out yet, and Klecker recommend only using filed-expedient handles when needed, as they can't be readily depended on, but it sounds like a fun activity.

So, all in all, the KLAX succeeds in providing a very useful tool to use in a pinch. It will do a good job at a lot of small tasks, but won't replace a full sized dedicated tool but packs a lot into a small package. Just my kind of multi-function tool.Check them out at this years NSSF SHOT show, on right now.

Wish Lust: KickStarters - RECON 6 Watch & KLAX

From time to time I either get forwarded, or read about some great ideas going on via Kickstarter, or other crowd-sourcing sites, and I want to boost their signal to help them out, as well as getting some gear ideas out to you folks ....

check these two out...


From the creator of the Crovel Extreme comes this jam-packed survival watch.

In his words:
*******************

RUGGED AS IT IS USEFUL:Recon 6 Watch is the Baddest watch around: Compass, Signal, Can Opener, Fire Starter, Whistle, Cutting Tool!

The most multifaceted utility watch you'll ever own.  Life in the great outdoors is no fashion show, but there is a tough and rugged accessory I am getting ready to launch that not only lets outdoorsmen make like Grylls, but could also save your life.  I created the Recon 6 Watch to tackle the unexpected and perform multiple tasks. Inspired by the desire to always be prepared, a cross between the Swiss Army Knife and MacGyver will take this multi-featured watch to a whole new level.  After months of hard work, my idea is almost ready to become a reality.

As well as a bezel equipped, phosphorescent handed and anti-chip and glare faced watch, it also features the following survival components
- Multi-Tool
- Blade with sheep hook design for dressing out small game
- Bottle opener
- Can opener
- Fire striker
- Signaling mirror
- Fire starter good up to 5000 fire starts
- Aluminum rescue wistle
- 25 ft. of braided fishing line with 2 small fish hooks
- Magnifying glass
- EMP proof, liquid fill compass
- LED flashlight

Hefty, and with a price tag to match, but packed with content....

Then there is the father-son team behind the quite innovative multi-tool, survival axe, which I have my eyes on.

In their words:
 *******************
The KLAX is a multi-tool built into the head of an ax.  It allows you to attach the ax head to a handle quickly in the field.  It uses the nested clamping system shown here.   The clamps rotate out from the handle for use.


The KLAX is designed to be a short term solution to many of the problems that you could face either planned or unexpected. It will help you to get through situations where carrying a full set of dedicated tools is just not possible or realistic. Here are a few examples...
- stuck on the roadside in the backwoods and need to build a lean-to for shelter
- injured hiker needs an impromptu travois (stretcher) to be carried to safety
- hiking and need enough wood for a small cooking fire
- hunting and want to make small game traps
- forgot the hammer and need to pound in the tent pegs
- starting the split on a small log without many knots
- need to dig a hole (let's see your multi-tool do that)
Bottom Line: If you think it is trying to replace your full-sized dedicated tools for everyday use, you won't be happy with the KLAX.

KLAX-Lumberjack  Our high-end stainless steel model with the most features.  The first three models are all made from heat treated SUS420J2  stainless steel which is perfectly balanced for keeping an edge and maintaining strength.

KLAX - Woodsman   Our mid-level stainless steel model with just the more useful features.

KLAX - Feller  This is our more rustic model with just the basic features you need in the outdoors.

Ti-KLAX is a Titanium version of the KLAX – Lumberjack and comes with all the same features, but because it is made from more expensive Titanium, it weighs only half as much as the Feller and is stronger than steel.  The Ti-4452813 titanium is also anodized to provide some eye catching highlights.

So, some pretty cool concepts there ....


I wish I could back them all, but we'll see, and perhaps I'll get to show them off in good time.
