Working with the BWM CG .... brief review

When I first got my BWM CG it came with a half decent edge sharpness wise but was a bit obtuse on the angles .... the classic Busse edge really .... one that is designed for abuse as well as use .... you could have a go at a breeze block with it and not worry about tearing any metal off the edge. In normal use tho' it can still deliver respectable performance ....

If you were after making fuzz sticks or curls of wood to act as kindling to get the fire to start you could certainly get them from the knife "as is" from the factory ....

These will certainly get a fire going ... even if you were in need of using a ferro rod they will still "take" the spark to a flame if mixed in with some dry dead standing reeds or twigs .... but what this type of edge looses compared to a more acute sharper convex grind is the element of control on the cut ....

It will easily remove the wet bark from sticks as above but when you go to make a fuzz stick it is likely that you will get one or two curls going and then when going for the third the blade might hang up a little and need a bit of "umph" to keep the cut going and once done you find you have powered through at the base of the cut and lost all three curls to a full whittling cut and if they are on the wet floor the benefit of them being "dry" is lost. That's why when cutting fuzz sticks I do it with a jacket on the ground to catch those curls which go astray .... sometimes if wanting the job done quicker it is easier to just go for collecting the curls on the jacket from the start ....

On the chopping front the factory blade is good .... the knife has that "key" feature of feeling nicely blade heavy which combined with the advantage of a light overall weight means the knife should chop well .... it certainly had no problems with smaller tinder ....

On my example I noticed the grips had a few edges on the pattern which I would prefer to smooth down but for smaller stuff like that above it did'nt matter .... it is only when tackling a job of much bigger girth or needing multiple sections of log cutting that the grip comfort really gets noticed ...
and on batoning it works well as is ....

But inside the knife their is a fair bit of potential which is simply not "tapped into" .... bring on the paint stripper .... apply some careful work on the belt sander and you have a ghetto satin finished blade which you have fully convexed from the spine in a slight very acute curve to begin with as the blade is only 3/16 thick .... so just enough to remove the Infi dimples and clean up the scratches .... then nearer the edge give the blade a steeper tapering appleseed edge right to the apex so that it can really bite into the wood without encountering much resistance but leaving enough metal behind the edge to keep the knife strong .... here is a pic of the blade after I had finished the process ....

You can see if you look carefully where the final edge taper begins and with the handles a little smoother from sanding the knife was ready for me to see just how it would cope with something bigger ....

I had this old stump lying around which needed sorting out and I had burnt the remaining log section a fair bit just to harden up the wood underneath to see how the edge on the blade would cope ....

P1010190.jpg


The knife did really well .... amazing really on the improvement .... it was able to bite very deep into what was quite hard wood just under the bark where the heat had really dried it out .... then as we progressed down to the softer inner wood which had not taken the heat it really started to show what it could do ....

P1010191.jpg


If you look at the pic above and the side of the log which was not heated ...just below the blade is the V section I could cut out on the softer side using my normal method of rotating the log/stump to take the cuts from all sides .... much quicker than trying to power through the centre in one simple V cut .... and the depth of those cuts on the softer wood was quite an eye opener for me on how the re-profiled edge had seriously improved the knife ....

P1010192.jpg


Visible again on the remaining stump section above you can see where the first slice on the softer side had sunk right up to the spine ... the harder section on the other side was the only thing preventing the knife from going through this section of wood in around 16 chops ....as it was it took about 20 but if you allow for the KZ taking about 16-18 on perhaps a much more through hardened and more burnt section .... it does show how well the BWMCG can chop if you make the most of the thinner 3/16 steel stock and taper the blade down to a good convex shape ....
 
I suspect the CE models available at the Creek and the Ganza will work just as well .... and it is a radical change from what I remember of my earlier impressions .... the knife in this sort of spec is a real chopping machine .... it is light .... very effective .... and very comfortable .... smashing value too .... this knife is seriously all you would need. I went through the rest of the stump like a hot knife through butter .... very impressed with it .... it did look a little bashed up at the end of it but the handy thing with a ghetto satin is that it is easy to restore ....

I have to say I am a bit suprised at the level of transformation on this knife once fully convexed .... and very pleased .... maybe on my first outing with it I had'nt had my wheatabix :D but it certainly now "shines" .... I would put it up there with the BWM LE .... there won't be much to choose between these two now ....:thumbup:

Thanks Peter - always entertaining.

BTW - It is called Weetabix here. Not sure why the brand name change but it certainly isn't as popular as it is in the UK.

Actually ... lol .... I think I have spelt it wrong and it is the same over here ....:o I went off the "logical" spelling of wheat ...:D
 
I've developed an affinity for the CG BWM also--very solid, good-looking package for the price. Nice review, Peter--thank you for taking time to do that.
 
Great write up and pictures Peter. I agree, a stripped BWM CG is a beautiful tool that's all business. Did you sand the INFI dimples completely off? I left some because I was concerned I'd loose to much thickness.

Using a leather backed platten I could remove the dimples in the middle of the sides of the knife without losing thickness on the spine .... just hold the middle section on the top part of the platten keeping the spine above it and do a few passes like that where needed ..... I then put the knife onto the belt above the platten for a slack belted fully convex taper .... I lost very little thickness on the spine doing it that way .... :thumbup:

Oh, I see. Does that make it more like a cross between a flat grind and convex or would it still be considered a full convex grind just less pronounced? Have you weighed it to see how much weight diff. there is?
 
I have'nt weighed the knife to compare it now the work is done .... but will do ....

The dimples taken off by use of the platten leaves the knife as it was before grind wise ... I only used a light finishing belt to do this .... then to convex I changed belts to a much stiffer blue zircon and angling the knife into the belt to stop erosion at the spine I thinned it down on the sides to a slight angle .... not a deep one .... then at the bottom I convexed it more into the edge .... so yes I suppose you could say it is a hybrid of flat grind and convex ... given that the knife is just 3/16 thick you need to preserve the spine thickness and the thickness down to say a third of the blades depth .... before beginning to taper towards the point and then once near the edge you do a much steeper edge as if almost you were putting a convex edge on a straight grind blade..... HTH's in terms of understanding what I did ...:thumbup:

I just weighed the knife and it comes in at 21.4 oz's ... so it has lost about 2/3rds of an oz with the paint and the re-grind and the slight smoothing on the grips.
 
Thanks Peter- this knife has impressed me more than any other I own and I have a bunch:thumbup:. Also in a price range where one can bash on it without feeling bad. Great review on a fantastic blade. I think I might have to buy another.:thumbup:
 
Thanks for the in depth description Peter. I knew that cheap belt sander I bought would come in handy eventually. The only thing I've used it for so far is axes and hatchets.
