Chisel edge v others

[dcm007]

New to the forum and have not come across the chisel edge before - guess from the name the style of edge. Curious to understand the benefit of the edge and also the styles of knives etc these suit and maintenance benefits / issues

usually you hear the term chisel grind in pocket knives, in kitchen knives we call em single bevels.

Usually used in japanese cuisine, not sure if elsewhere. From what I hear they can give a cleaner cut with one stroke, like a yanagiba (long knife for cutting fish for sushi) but you need to be proficient with them, and you need to be able to "steer" them

Chisels are woodworking tools. Used for other many purposes including surgery, Sculpture, even Ice Carvings.

They are single bevel. Endless shapes of gouge's, V shape & flat. Sharpening them correctly is important just like Chef Knives.

Japanese single bevel knives like Yanagiba & Deba quality ones are actually slightly concave backside. The apex is reached when sharpening SB side a burr is created.removing burr with concave backside absolutely flat on the stone . Mistake is to overwork backside too much time on the stone that can compromise the geometry of the blade. However the edge on a Yanagiba is one of sharpest like edges achieved on Straight Razors.

Chisel grinds on pocket knives if double sided not true chisel grind. Term is used because large bevels look like chisel.

Many hand garden tools like jaws on loppers are SB, hand hedge shears. SB are used in industry for shearing off products.

As you can see, folders that are designated chisel are literally not ground on the back

 

[Keithpaints]

Wow majority of so called chisel grind folders I've seen are ground on both sides. Have tactical Pro-Tech double grind. Never looked for one sided folder, knew Japan had some. 3,200 for a folder nuts

 

[jedy617]

Yeah who would ever spend anywhere near to that on a folder certainly not me no sir

 

[pavhav]

not me no sir

Is that . . . sarcasm? It smells like sarcasm to me.

Oh hey, I found a soap box!

Neither of those are single bevel edges. Neither of those are chisels. Both of them are marketing gimmicks or lies.

The second picture of the second link makes it look like there is a 0.5mm tall bevel on the back, which makes sense, as a sharp single bevel knife or chisiles requires the back to be polished/refined to the same degree as the edge (that knife is not).... Which is way too much work for a marketing gimmick, but not for an actual tool.

Yep not true SB. Have lots of experience with chisels. Both wood & for Ice Schulpture. Most of woodworking inherited from my Father. Tools of the trade 1936 as pattern maker at Newport News Shipbuilding & Drydock Co. In 1939 he switched to Langley Field Air Force base. 1938 NACA had built large windtunnels because USA was behind in aircraft design later became NASA when Russians sent up Sputnik. Last surviving wood relief I did others sold or gave to family this one gone to my Nephew. Tiny gouges so sharp just hand push through the wood. Wooden mallet used on larger pieces. Ice chisels large both Stainless & nice carbon ones I bought in Japan.

thanks for this - had the link to a woodworking tool and wondered how that translated
