These were some of the most expensive knives to buy back in the day.
Working with this substance is dangerous to your health and when the knives were being assembled it was easy to crack it. The workmen that hafted knives in Pearl were the highest paid! Too bad it ended their life prematurely
Most every pattern knife could be bought with MOP, at a higher price, therefore you see very few large knives with it as a handle material. The few examples like E. Toenails that have it command a very high price from collectors.
Lots of tiny, small, and medium sized pen knives come handled this way, I even have a 15/16" charm knife in MOP. It seems every small scrap of this material was used and not wasted.
Some of this pearl is what is called "Firey", meaning it has color. Some of this type is very attractive.
Here is a Boker MOP handle Office Knife, firey mother of pearl on the front and back side! It measures almost 4" closed, so these are big slabs.
If you have any vintage MOP handled knives, big or small, Let`s see `em
