Blade thickness?

Is .070 too thin? I am looking at a new knife with a blade thickness of .070 and I can not get a feel for this. It will be a folder for general pocket knife type use. Very little rough use. Sounds like a great slicer thickness. Just not sure if it is too thin.
 
Hi,

My personal preference is for thin blades, because they are nicer slicers. So I would buy it.

To visualize .070, it's about as thick a quarter.

I'm with Dale thin blades are fantastic!!! As long as you do not twist and keep the pressure on the cutting portion of the blade you will be fine. In fact, once you have a nice thin blade it's hard to go back.

They're even sturdier once you get the blade length down to about 1 - 1 1/2". I have a few slip-joints with blades roughly that size and they feel rock solid.

I think my Old Timer Dogleg Jack is about .070"... Could be more like .050" though, I don't have my calipers on me so I'm going by eye.
 
Thin is good.

Just for a perspective, how thick is the blade on a Stanley utility knife?

And then look at how they get abused on job sites.:D

0,070" is 1,7 mm more or less
so it's a fine thickness

i think there are "pen" blades or sak blades that thick

(ehm my conveter was set non in inches so meesed it LOL)

0,070" is 21,34 mm more or less so it's a fine thickness for many uses

saks are I belive around 2mm right?

Wait what.............. :confused: :D
You are saying that a blade thickness of 10 X that of a sak is a fine thickness for many uses. :rolleyes:

I belive 0,070" is closer to 1,75 mm ;)

The size of the blade and profile could make a difference as to whether or not .070 is the best choice for this knife. Keep in mind that a properly heat treated blade of this thickness is an extremely tough blade if used as intended.

I can give you a few guidelines that I try and adhere to when making a slipjoint.

Most master blades in the 3 3/8 to 4 inch. .093
Most master blades in knives over 4 inch .115 to .135

Most secondary blades in 3 3/8 to 4 inch .070
Note: 3 5/8 to 4 1/8 stockmans/cattle the secondary's will be the same as the master .093
Note:Please keep in mind also that many blades in mult-blade slipjoints may have their blades "offset" ground thinner than the blade stock or tang.

Most whittler secondary blades will be .065 or .060

Please keep in mind these are just general sizes. Also keep in mind the grind. A flat ground .093 blade will have a bit more material than a hollow grind. If you take .070 and give it a 10 to 14 inch hollow grind it will be a thinner, less robust blade than a comparable blade that is flat ground.

Depends on how long the blade is.
Here are some blade thickness measurements for comparison.
Buck 303 master blade at base_____0.74
Vic Tinker master blade at base_____0.84
Buck 301 master blade at base_____0.90
 
I used to think of a knife as a "hard use tool". One tool that can be pressed into multiple jobs. I have realized the error in my ways and now understand that a knife should just cut stuff. The knife I carry to work has 2 blades that are a little over 3" long and they are about as thick as a quarter (about 0.70"). I work as a remodeling contractor and I have never had a problem with it, I doubt the OP will have a problem with a similar style blade. I don't think that lengh matters as much as how you use the blade.

This is a great thread that helped shape the way I think about knives.

I decide to put a micrometer on a very common medium framed knife for comparison, the Case #62032 CV Texas Jack.

Main Clip = 2.553" tip to bolster, open, and 0.070" thick, just in front of the plunge
Secondary Pen = 1.760" to bolster and 0.056" thick (measured the same as the clip)
