Just discussed this with someone yesterday lol. The paper could not guarantee the similar quality. My personal experience, there were 2 tachi from the exact same smith at tokubetsu-jyuyo...but they are priced more than triple difference. IMHO the cheaper one also in great quality and deserved toku-jyu designation. Seeing them in hand I kindda understand why. All factors like work quality, deki, style, health, length, nagago, condition, mei, denrai, popularity and completeness are factors we include for "quality" as a whole...and yea one of the toku-ho blade you see might have be a toku-jyu candidate...who knows?
