I was rough hollowing a sweetgum bowl when about 1/2 inch deep I heard
and felt a whop-whop. Stopped the lathe and there was a cross section
of an 8 penny nail. My Benjamin's Worst bowl gouge had a couple of
notches in it. So I gets out my oland tool with the 1/4 inch tool
steel tip and continues the hollowing. When there was no more nail I
checked the edge of the tool. Still sharp and no notches. Sure beats
taking the bowl off the lathe and digging out the nail.

If an experiment works, you must be
using the wrong equipment.

Yep, I use the Oland tool so much that I've made a 2nd set in 3/8"....
Sometimes, it's just the tool to use and nothing else quite works..

I usually have 2 or 3 of each size handy and sharpen them all at the same time..

Any idea why? The BB tools are HSS. What sort of tip did you
have in the Oland tool? All the oland tool roll-yer-own instructions
I've seen use HSS as well.

Maybe that the oland tip is sharpened at a more obtuse angle. Maybe it
is a different type steel.

I'll bet on #2. In Alan Lacer's metallurgy article last year he
found that one BB chisel (bought from Penn State) was M2 steel, while
one bought off eBay was not.
I've since heard that many Chinese made HSS steel chisels are M1 (ie
not up to M2 standards)

I hope you weren't surprised.

The next better material - harder to get in large bars I suspect -
is M42 - It is harder and stronger yet.

M1 is likely used on the grasses and light woods in China.
Grasses - bamboo...

M2 is a metal cutting steel like M42. It is used in wood for
the tough ones - those with silica.

I turn wood and metal and machine metal.

There are bowl gouges with short blunt edges while there is a
fingernail cut with long cutting/shearing edges.

Every cut Bamboo, tough and gritty. Almost as bad as Rattan (I get
sparks off Rattan!!!!)

D-way Tools uses M42. So far I like the quality

In my experience, the Oland tip survives more abuse because of the cutting
angle, the narrow profile and the fact that it's basically a small, thick
scraper..
A bowl gouge has a flute and thin cutting edge and while it produces fine
shavings, it's also much more prone to dulling and nicking, IMO..
