Hello Guys in the intrests of knowledge within our community here is some more information further to the sticky thread "20th century Military Pattern kukri." I wrote a couple of years ago. I realise this isnt to evryones intrest, but if it is enjoy!

The mk.4 is to date the rarest official British issue kukri pattern model to ever exist, and the last 50+ years have made it virtually unobtainable. Only 8 that I know of & one of those was repired with replacment bayonet type rivets & another was a heavily cleaned up battered relic, {as seen on kukri FAQ.} only 3 had original scabbards & one of those is kept at the Gurkha museam.


It was designed in 1949/50 by Wilkinson Sword Company. It appears the British army wanted to buy British despite the much higher cost rather than keep purchasing from The Indian kukri factories. One Army source is quoted from a letter to Wilkinson sword as saying they were fed up with the fast wearing out of the then currant issued kukris. {rather implying a soft steel or untempered edge perhaps? Typical of some 50s era Indian & Nepali kukri more suited to tourists than military use perhaps? ]

In profile the WSC 51 looks nearly identical to the mk.3 which was obviously its design basis but when examined by hand their are many subtle differences. Chroming of metal grip parts, precise tolerances & most fascinating a totaly hand ground but not forged blade to an exacting finnish.

The Wilkinson Sword manager before they closed down confirmed to me that only 1400 were ever made, historicaly in Flooks research he came across the same figure. I had emailed them as I was lucky enough to obtain one of the 2 known kukris Wilkinsons kept. {One in there "museam" & one as a pattern in case of any further orders.} Mine was the Assembled pattern one & rather wanted to check it was officialy "on leave" that's when I first heard they were sadley closing down the sword division.

1400 is A minute number for an army production run. Less than 10/% of serving Gurkhas would have been ever been issued with them. One company was recorded by letter many years later as not liking them as the steel was too hard,I am also sure some Gurkhas wouldn't be keen on it as after all it is a full tang kukri which just doesn't feel the same as a traditional model, full tang alters the balance & feel to a more western type of feel. That's probably why historicaly they often bought there own kukri rather than using the mk.2,mk 3 & I am sure probably the mk.4. as well & its wood choice for grips is not perfect for slab grips but it still far exceeds any other general post ww2 kukri in usabilty & quality.

But stories of them throwing them away or being without "souls" sounds highly unlikely in my & some others opinion. The current British SA80 bayonet is probably the worst & cheapest bayonet in military history. So is the current version of the issue kukri , They still often carry them though.

There is photo evidence of Gurkha signals carrying WSC 51 kukri in Malaya in 1953 & several of the known ones were marked with a Broad arrow & 48/J this is also a clear & positive reference to a Gurkha signals unit based in Malaya as a little study of unit nomenclature clearly shows if one takes the time to research.

They where a very high quality production by some of the worlds leading sword smiths & cutlers.Presumably the cost of having them made by WSC resulted also accounted in no further orders at the time. Intrestingly in 1969 approximatly 10 years after the current often poor quality MK.5 was introduced, 20 years after its intial design, the Ministry of Defence obviosly realised there error & tried to get Wilkinson to discuss filling futre kukri orders for them. Reading between the lines it seems Wilkinsons didn't really want the buisness, although varios papers & plans seem to have been intialy produced but then not sent to MOD.

What happened to many of them is sometimes regarded as a mystery , I have heard many unsubstantiated stories, but it seems to me the simple truth is they most where never brought back out of Malaya ever again they were used to destruction in the longest jungle campaign fought by the Gurkha in there their long & bloody history. Thier grips were made of beech, not the best choice for wet or tropical climates.It is possible a few are tucked away still in eastern military armourys but dont hold your breath! It might just be wishfull thinking!

Personally I cant see any mystery, A couple of years never mind 10 or so years in the Borneo jungle would rust & rot most equipment beyond recognition. According to army sources canvas jungle boots & webbing would be rotting within 2 weeks.

Hence I think the rarity of the mk.4 Wilkinson sword kukri. Not many were made in the first place, Then in that extreme environment some handles eventually warped or rotted & Loosened the unless cleaned & oiled every day the steel rusted. {As it did on all equipment in Malaya.}


Much of the Information in this thread his has been confirmed by & in some cases come from other acknowledged sources including the famous British author of numerous sword books & worldwide acknowledged sword expert & the best authority on Fairbairn- Sykes knives known , Robert Wilkinson-Latham, A descendent of many Famous Wilkinsons before him. {He has a fascinating Commando knife website that also lays to rest many old wives tales about the FS knife to rest, that we often here regularily regugitated.}

http://wilkinson-fs-knife.blogspot.com/

He even kindley after coming to this forum & reading many of the recent posts & hearing of my current work kindly entrusted me with a pile of the original hand drawn WSC kukri blueprints to copy & study to aid my research into this fascinating kukri. I am honered by his trust in sharing these irreplaceable & fragile original documents with me. He has been a great help on this & other sword & knife related questians as well, a man of true knowledge & expierience in his chosen fields. We are luckey he was brought to this forum, its an honor to work with such a man.

With the quality of workmanship to exact tolerances that went into them & thier place in Britsh swordmaking & Gurkha history in Malaya, it seems rather a shame that further orders wernt taken up. The popularity & reputation of late 20th century kukri would have stood much higher if they had. But luckily it gives most realy serious kukri collecters something to search for!

The scabbard fits better than any other scabbard I have seen, it stays in place even upside down but 28ozs of pull {only 4 oz more than its weight.] & it slides out like lubricated silk.


That's why the last well used but not abused one without scabbard I saw for sale didn't sell despite offers of £350, the owner said he would rather keep it than part with it for that. A good scabbard & frog easily double that price. If you can find one.


Heres a few close ups of the WSC51.

Enjoy!

The first one shows the chrome plate on the handle tang to prevent rust from sweat! Now that is fine attention to detail. The egg shaped buttcap is similarily treated.

Because of their rarity, I wonder how much one would be valued at in today's market?
 
Thanks Spiral! Interesting as always and indeed a high honor to be trusted with such documents!!!!:thumbup: :cool: :D
I'm curious about the two kardas as they appear quite small and very thin compared to the ones made in Nepal/India by the kamis?
The handles also appear to be shorter than common, would you please post the specs on both the kukri and the kardas?
 
This is the style of kukri I started with back in 1987, although mine was a lesser kukri made in india and sold by a well-known knife retailer based in Atlanta Georgia.

I still have it.
 
Fascinating. When you mentioned the chrome plating on the tang, my first thought was, "These guys thought of everything." Was a synthetic handle ever considered for this, or was wood planned from the start?

If your blueprints mention it, would it be possible for you to post some of the technical details here for our enlightenment? I'd be particularly interested in reading about the alloy and heat treat protocols used (or more specifically, the target hardness), edge width, and point of balance. Any of your personal observations about it would also be welcome.
 
Priceless bit o' two nations' heritage, right there.

Like looking for a rare penny in your change, any one of us just might trip over one someday.

Very cool and thanks for sharing.

:thumbup:Thankyou guys, a lot of the credit really must go to Robert though.

Moblues...Currant values Id estimate as per.original post. but realy its hard to say what the next one on the open market would fetch if correctily identified.

I'm curious about the two kardas as they appear quite small and very thin compared to the ones made in Nepal/India by the kamis?
The handles also appear to be shorter than common, would you please post the specs on both the kukri and the kardas?

The kardas are 6inches long Yvsa, blades 3.5 in handles 2.5 inch, very thin but rigid & unbending. ,

Made of same grade of Wikinsons tool steel as the kukri & hard enough to mark the blade, so clearly capable of easily honing.

The grip has a slight rounded rectangle profile , reminding one of a cavalry sword or rounded butchers knife, great for grip when things are getting slippery. Clever how they round it in to ann egg shaped butt as well.

Weights 26 oz, so thats only 2 oz. extra pull to take from scabbard, but realy does fit like an expensive glove.

Wood seems to have been the only option as far as Robert & I can fathom, Dave Personally I think English walnut would have been a better choice, but possible due to "penny pinching" by MOD as they clearly were trying to bring the price down at the time. Sythetics could have been interesting but I think Wilkinsons was fairly "organic" usually in their choices?


Some parts of the story & specs I am not free to divulge at time bieng & some things were still researching.

But the steel spec isnt one of them.;) Robert has letters showing, that The kukri & small knives alloy mix was made to the Wilkinson specification & ordered in 20 tonne ingot.

Spec:
Carbon---0.90% to 1% Max
Silicon ---o,20% Max
Manganese ---0.15% to 0,35%
Sulphur --- 0.2% Max
Phosphorous ---0.2% Max

Which is apparently very near to BS 1407?

Wilkinsons insisted on this spec because as stated '...we must have steel to our spec because the blade smiths know exactly where they are in relation to the heat treatment process.


The top plate of the Kukri was CR4 Mild Steel ,as was the scabbard chape. Both chromed.

I can hopefully come up with more info at a later date, We are working hard at deciphering & interpretating some of it & there more possibly more files as yet storage.

Balance point is 2 1/2 inches in front of grip & happily sit on a thumbnail.

Hardness is a fraction under file hardness, the target figures I havent spotted yet, hopefully they still exist.

Ad Astra, I was lucky enough to find one as an "old machete" on ebay a couple of years back, complete with scabbard & Gurkha signals markings, got it for just on $100, I think that was with shipping as well.

The seller was delighted as she paid $22 for it at some School fundraising type sale somewhere in California, She was concerned that I paid such a high price for it that I might not pay up! So I just said, "I am sure its worth more than I paid."

I was scared she might not post it!:eek:

Luckily she did! :)

Dave, further to your tempering & hardness questian heres a fuller answear from Robert that you might find interesting.

I found it fascinating!

Hardening and Tempering.

Basically any Wilkinson blade was treated as follows:
After the blade had been forged it was sent to the Grinding mill to be ground to the correct dimensions. It is then returned to the Smithy and is hardened by heating in a gas oven to the required temperature and then being immediately quenched in Mineral Free Oil which does not impart any change of character to the steel.(At the risk of offending in this day and age but in need for accuracy in research - up until the 1960's, this oil used to be Crude Whale Oil).
the blade is then tempered and made flexible by the immersion on a bath of molten lead and finally is straightened by hand and eye on an anvil using a fixed fork. Finally the blade is immersed in water to cool it. It is then subject to the Wilkinson proving and bend testing before being polished and then acid etched or stamped with appropriate Government marks etc.
As you can imagine, over the years this skill of guaging heat by colour of the steel is passed down from one 'Smithy' to another BUT in the modern day and age we have to have a known and written down benchmark!
Hardness checks were made on Wilkinson Sword steel used for swords and a 1951 memo during Kukri manufacture stated:
"It is essential that hardness checks are carried out after quenching and before tempering of the Kukri blade units. then again after tempering to ensure hardness is under 500VPN, say 450 to 500VPN before subjecting the blades to the striking tests."
This test was using done a machine to strike the blade on each flat and on the back or spine of the blade and then a separate test on the cutting edge.

Hi spiraltwista,

Great post on the Wilkinson WSC51 Kukri !!!! I read you post back in 2009 on this Wilkinson Kukri and was fascinated by it.
I am a novice when it comes to collecting kukri and I know that there is limited number of the kukri existed making it a holy grail for collectors.
Christmas came early for me this year. As I am writing this reply, I think I have found the Holy Grail and it is on the way to me !!!! Here are some pics of the Wilkinson WSC51 that I have found.

I will be keeping this Wilkinson WSC51 Kukri
I would very much appreciate if you can help me with the following questions:

1) Is the sheath and frog original to this kukri??

2) Should I keep it as it is?? Or have it clean and sharpen?? ( I will not be using it)

3) Is there a WSC51 registry to record who owns one of this kukri??

Thank you very much for all your posts on kukri. I have learn quite a lot from your posts.

Cheers.
 
Hi! Thanks for your pm at IKRHS, sorry you had trouble uploading pics there, the software is a bit outdated & none of us are IT guys.

To answer your question, yes frog & scabbard are correct original Wilkinson sword product.

Cleaning the blade with baby oil & 0000 wire wool would be good.

As a collectible best not to sharpen, if its a weapon & your going to war, or wish to use it tool, then sharpen it.

That may reduce its value somewhat to some future collectors of kukri though, if ever sold.

Its a good find, I only know of about 20 of these in various collections around the world. {One chaps got 7 of them!}

Hi Spiral !!!

Thank you for your response to my questions. I am not much of an IT guy myself too.
Hopefully I can figure out how to upload these pictures on that forum to share it.

I hope someone can create a registry to track all the existing Wilkinson WSC51 kukri and its owner around the world.

Cheers
 
Sure love to find one of these myself. Great piece of history and very special.
The odds aren't good but I can hope.
