Blade design of first knife.

If you are going to call yourself "The Geek" don't call any angle less than 90 degrees "Obtuse".
 
A 30 degree angle is more obtuse than a 15 degree one, so the geek's use of obtuse was correct if only a bit confusing.

-Frank the Tank
 
Pretty sure a 30 degree angle is just less acute than a 15 degree.

Obtuse is greater than 90, less than 180.

40 degrees is not acute enough to be a real useful bevel.
 
Yes, in the context of obtuse meaning not acute, not sharp, or blunt, it could seem to apply in some cases.
Since the knife edge being discussed is acute, is sharp, and is not blunt, it really doesn't apply in this case.
When the term is applied to angles as in, "a 20 degree edge angle", obtuse means above 90 degrees and below 180 degrees.

I agree that this is knit picking and I should have let it pass.
 
You were cracking a joke Stacy, and inadvertently educating folks.

I'll bet you an alarmingly high percentage of adult Americans don't know the difference between an acute and obtuse angle.

Never mind a reflex angle...
 
OK, now if you have a glass of water and the water in it is exactly at the half way mark, is it more full, less full, more empty or less empty?

More full than a quarter of a glass, less full than a three quarter filled glass...

Less empty than than a quarter full, and more empty than a three quarter full...

Gotta have a baseline for a more or less proposition.
