All About Pocket Knives

Hello. Would anyone have any info on this Bulldog knife? I bought it over 25 years ago.
The only markings I can see are the words bulldog and the picture of the bulldog.
My son is starting to collect knifes now so I’m going to give him some of my collection. But also don’t want to make mistake and give away a hard to find knife. Wouldn’t want him trading it away/ any help would be appreciated

they where made in pakistan was only inked onto blade and easily rubbed off

Knife is about 10.00 new, made in Pakistan and passed off as a Bulldog Brand frequently. No bulldogs were made in Pakistan.

What others have already added are quite true and I wanted you to have a little more information.
Case made some knives that they also called a Bulldog pattern because of the size mainly I think, also Bulldog Brand knives were made in Solingen, Germany. Mr.Dorton never made a bulldog pattern like this for Bulldog Brand Knives.
