well some are. mostly they are FAT behind the edge so taking material off where OP had indicated is beneficial to the overall performance.
I've had both convex and the above mentioned fat behind the edge blades. I've removed material from both types using the method described above with much...
it is very doable. I've done this exact thing to MANY MANY Busse combat and Swamprat knives.
Use that sharpie on the edge up to past where you want to remove material. if you go really slow you will have zero issues removing exactly the material you'd like.
you can ALWAYS take another pass...
sounds like someone did someone else a solid.
I've always been amazed at the generosity between members of the knife community. it's a joy.
otoh. I'm very sorry to hear about your wife. God bless you and your family.
well. I machine titanium for medical parts so it may be different. I use small diameter barstick in swiss lathes.
the tooling lasts quite a long time and dimensions dont move at all.
this is grade 5 Ti wich has the least pure titanium.
I know that pure titanium gets pretty gummy and...
not much. I learned that I should probably keep practicing trigonometry as it is useful in every day encounters.
hopefully I wont have to think much more today and that brain wrinkle can smooth itself out again.
It gave me a cramp.
