I think Plumb was effected by the new model effect. I had a yellow let go after I poked at it for being higher than I thought it should be. A new yellow issue era for certain. Out of a number I will not disclose but gives me good data, I have had one older knife, bolt and hammer shield jump ship. I have seen about five or six for sale shieldless on the auction site.. I think Mr. Knarfeng is correct in his opinion that this malady effects very few in the over all aspect of things.
I will say that, yes, as a supposed collector when I see special efforts to go the extra mile, such as riveted shields, I appreciate the crafting of that knife more.
Again, I do not worry about that on the black sawcut 300s with there pillar/liner attached method of shield construction. What I will be a critic of is the amount of gap left around the new blue shields on the dymondwood models. I wish it could be smaller, but that may be a manufactoring limitation. But I still wish.
