Thank you for the comments. Ergos have always been really important to me. For the most part using a blade should come naturally for its designed purpose. I wouldnt say this is difficult to achieve you simply have to use the knife patterns you produced. Pretty simple really.by KWB - Say hello to my little friend!
Its not that it wont hold at 10dps with more thickness behind the edge. But when the primary is below .005 I found it to roll or chip.by KWB - Say hello to my little friend!
Oh I always do, but it doesnt seem to matter with the occasional buyer, they think its is adamantium.by KWB - Say hello to my little friend!
Ime- m390 is doesnt hold low edge angles very well with bte thickness below .010. But cant see the point in high edge angles and bte super thin thats just asking for trouble for anything other than light cutting. I have just become so use to aeb-l with stupid low primary and secondary bevels I guess I prefer ability over duration. For myself I prefer a thin belly slightly just slightlyby KWB - Say hello to my little friend!
How much do you think by percentage of edge retention is lost by chisel grind in everyday use?by KWB - Things to read in Denver when you're dead.
All very true however, it may be difficult for the average user to describe what they are seeing with such exact descriptors. I guess its all what audience you are speaking to. When I go to colleges for some of their enviormental symposiums or speak with professors. I often find myself asking "what does that mean in plain English?" Its not that I dont understand conceptually ratherby KWB - Things to read in Denver when you're dead.
I follow now, when someone says edge I think of the part you can easily see secondary bevel. But as for apex I can believe that for sure. What I mean by soft is in the 54-58 range and or overheated.by KWB - Things to read in Denver when you're dead.
When I say difficult I mean harder than say .125 simply because their is more meat between the grinder and your fingers. I grind freehand and its awkward to use a rest. But it does take care when mirror polishing such thin steels as they heat up so quick. Interesting you state roll the edge as opposed to deform or chip I havent experienced rolling except in very soft steels.by KWB - Things to read in Denver when you're dead.
By that math the average user is going to simply use feelings as to whether the blade is good or bad.by KWB - Things to read in Denver when you're dead.
I made a few chisel grind knives mostly and specifically in extremely thin stock .050 and under simply because its difficult to grind. Cant say I noticed any large changes but then again these are essentially pairing knives. Also I sharpen them like I would a regular knife. The cool thing about chisel is the ability to lay the blade flat on a surface to cut and the surface acts as a guide. Thby KWB - Things to read in Denver when you're dead.
Interested to see how the two compare, I did grind that one thin. I could have ground it much thinner sort of how Kyley did with one awhile ago, however I still wanted it to have some essence of "yeah, it will cut that". Without after cutting " Did I chip out the grind?"by KWB - I am kind of a big deal.
Logically that makes sense, however in my experience its simply overuse.by KWB - The Wood Shed
Be cautious with grippers you can really twist yourself up. Best I got to was 1/4" away from no 3. If you want more hand strength wrist wrench, levers with sledge hammers. Nail bending is much more fun than grippers and you can develop nutty wrist stability.by KWB - The Wood Shed
Unfortunately It is slightly more complicated than that. A large portion of run off is due to farmland. Not picking on the farmers they are using what is their best option. But compacted soil, sprayed and tilled year after with little or no biodiversity what is happening will continue. Forests are really not so much of an issue the soil is balanced, reatains moisture, slows erosion etc etc. Thby KWB - Nothing under the microscope
Biochar contains a large volume of air. When it rains it also retains moisture, npk, removes heavy metals etc. Think of it as a soil enchancer. If anyone has real interest I can go further in depth. The problem is cost (non subsizedizing or carbon crediting yet) $150-$600 per yd. It doesnt take a lot of calculation the only viable space for it currently is home garden, high yield low space grby KWB - Nothing under the microscope
Jsct, actually it is. It remediates them.by KWB - Nothing under the microscope

I chopped through so much nasty stuff with it I sort of forgot how thin and lean it was.by KWB - Say hello to my little friend!
I suppose it could use that extra strength......by KWB - Say hello to my little friend!
No, it will be some time before I can get to it. Super busy at my primary jobs. Maybe jsct will do it before me.by KWB - Say hello to my little friend!
I think it is imperative to state stock thickness and blade width, people get way to hung up on only edge thickness and angle. Your primary grind geometry is really where you see a huge difference. And sometimes its not even the grind but the handle, I wish this was talked about more I have spent a great deal of time improving my ergos with every knife. My favorite handle is an hourglass withby KWB - I am kind of a big deal.
The proto will be for myself, pretty skillful with a blade but I have the capacity to destroy anything less than plain tough.by KWB - Say hello to my little friend!
Mower- yes that may work, however it will induce stress to the blade if not done at forging temps, my mirror hammertone also does this but the blades will never see that heavy of use to matter. Jsct- that all seems reasonable however at this point without knowing if it will actually work, its kind of like planning what type of wheels to get for the car you dont have. Cf is very strong butby KWB - Say hello to my little friend!
Pretty diffiuclt to put a fuller on such a blade, but I do not think taking away more metal would make it stiffer. Yes carbon fiber.by KWB - Say hello to my little friend!
As an update- anyone who has a chopper should also have a machete such as this. Thin blade, thin stock pretty much the same thing they use to prun x mas trees. After using this for awhile I honestly dont remember how I managed without. Full disclosure the grind did roll in one spot from hitting small dead oak branches from a pin oak. This was fixed after 2 sharpenings. Anything over 3in diameterby KWB - Say hello to my little friend!
Thanks guys, that is burlap micarta. Jsct- this is true, although micarta wears at nearly the same rate as steel. Makes things super flush.by KWB - Say hello to my little friend!
Here is some of the latest work, some notes been doing dovetailing and working with higher end woods and also have been hiding the pins, I was afraid it would turn out well and they did, now I feel as if the higher end knives should all have hidden pins. It gives it such a clean look, as far as function no benefit that I know of plus takes time. The last one I was going to sell but when I saw howby KWB - Say hello to my little friend!
When compared to traditional industry standards of toughness such as those used in say chipper blades. Really not that big of deal really it will work fine, its just not ideal. Sometimes people outside the forum browse these threads, some more than you would think.by KWB - Say hello to my little friend!
