Traditional knife homework - Blade length to handle length ratio.

Off topic, kind of.
You wouldn't want this falling on your house!

Didn't read the full thread but I love seeing how we have measurements to three decimal points 🤣

I'm surprised we don't have any insurgency on why we are measuring them in "inches"!!!

THERE’S a twist that didn’t occur to me…

I’m sure the measurements are in 16ths of an inch - all those decimal places come from converting the 16ths to decimal with a calculator :D

I’m pretty sure the engineer’s scale is just in there for the photo-op

It's the nature of our fractional measuring system. 1/16 = 0.0625 ~ 0.063
I'm perfectly happy to use metric, too, but I was in my unmentionables and on a mission first thing in the morning.
this kind of math can't wait for robes, finding a metric ruler or imperial vs metric debates.

You could also use 100ths of a foot, as I’m sure you know, but you would have to estimate the 1000ths to get the same precision. You will notice the wooden ruler I used also has 100ths on it. The other side has scales for the corrections needed to measurements made using a 100’ steel tape due to temperature (nobody does this anymore I don’t think, but for some reason they still send you the little ruler with the tape).

Yep.:thumbsup: I was doing my measuring to the nearest 1/16" and/or the nearest mm with a tape measure showing both scales - then converting via the calculator. That's close enough for me. :)

My usual maths innumeracy & banality...but I think the Spear 99 lockback is killer (if you get my meaning :eek::D)

I get it Will !
O1 tool steel. Pinchable, smooth walk, loud talk, perfectly centered blade, no play. The first GEC i bought. In my pocket everyday since 2014.
The 47 is at the same level. The primary grind was so wavy that i ground it on my stones. The narrow secondary bevel you can see is at 10 dps. A pocket razor.
The 35 was uncomfortable both for carry and use. I've filed the "screwdriver" and the hook of the secondary blade. It's not my most beautiful knife but it's a true workhorse.
The 62 is perfect in all respects. The best whittler i've ever used.

Well, i can say i do like the Farm & Field lineup.
