My reviews:
Yaqi Telstar SS razor:
I don't have the RR Lupo so I can't compare but the Yaqi Telstar is an impressive razor!
Full stainless steel with a beautiful machined/brushed finish.
It is an efficient razor, and fairly comfortable.
The shave reminds me of the karve E plate.
It has fairly high blade feel but despite this, the blade control is good, with fairly low blade chatter. The face feel would also be around the karve F plate.
Riding the cap works better as the blade lays fairly flat in the razor head without a pronounced blade bend.
Yaqi Tile SS razor:
The Yaqi "Tile" has become one of my favorite razors!
It's essentially the Henson design but in heavy stainless steel, which made all the difference as the lightweight Henson AL medium didn't work for me as all.
Aluminium razors like Henson, ATT and karve didn't work well for me, just couldn't get through my stubble without pressure and momentum!
The Yaqi Tile is brilliant! Minimal blade feel, zero blade chatter and just so comfy, smooth and efficient.
The angle is so easy to find and it works awesome riding the bar (which is the angle automatically provides due to the flat surface).
Efficiency is around the karve D plate, perhaps a tad higher, but with muted blade feel due to the zero chatter design. The "face feel" or blade feel would be a bit less than karve C plate.
The blade has a very extreme bend, pinch point is near the edge and the blade reveal is minimal (essentially just the cutting edge). These factors lead to a razor that provides medium/high efficiency with minimal blade feel and ZERO blade chatter.
This combination makes problem areas much less work than compared to razors that may have "aggressive numbers" but still cause issues such a blade chatter and feel harsh on the skin, whilst providing the required efficiency.
The Yaqi Tile removes these negatives whilst maintaining the efficiency.
It reminds me of the ATT Windsor H, which is one of my favorite razors due to its minimal chatter and high efficiency.
I love the razor with sharper blades like Polsilver and BIC chrome platinum.
The BIC is sharper and ultra smooth in the Tile.
The Henson head is a game changer in razor design and that design combined with the weight of stainless steel has truly blown my mind!!
