Yes IP, true.
What we see & believe when we're on the outside looking in is very often a lot different to what we find the truth to be when we're on the inside, looking out.
It can be pretty disillusioning sometimes.
Going back into the late 1970's through to the 1980's the situation with forge welding & the associated craft of pattern welding was in the process of being reborn in USA & other places. A lot of custom knife makers, & others, wanted to jump onto the wagon and find out how it was done. Forge welded & pattern welded knives were the new thing. We were all going to become millionaires.

led the way, but a lot of us followed.
In those early days there was at least one WannaBe in the USA who found a quite skillful way in which to flim-flam the dreaming masses who wanted a beautiful pattern welded knife.
What he did was to make small pieces of pattern welded material, & then affix those pieces of pattern weld to a mild steel core in a mosaic pattern with good quality adhesive.
It is possible that some of the individual little pieces of "pattern weld" were also constructed with the help of adhesive.
Correction
I have just been advised that at least one of the people who made "pattern welded" knives in USA with adhesive --- maybe even the one I was thinking of --- did in fact use good, high carbon, heat treated steel for the core on at least some occasions.
