The blade has asymmetric plies design with different composite fibers. Inner white-black one looks like inside of my DHS Hurricane 301z, another blue-black looks like common ALC. Core is solid single piece wood. Top ply is not perfect but without knots or other major defects. Handle is has two metal tags: on one side and at the end (I have seen similar blade without metal tags from different shop). Minor negative: metal tag is on the inner ZLC side, presumably used for BH. The weight of my exemplar with straight handle is 90g.
Overall build quality and finishing is better then some more expensive European brands blades I have seen but not perfect like Yinhe blades have. But the low price of this noname blade with unique design is worth a try.
Comparing against DHS Hurricane 301z blade (with Yinhe Jupiter III Asia 39 and Yinhe Uranus Pro Soft)
1. Stuor blade is slower and softer. On 301z blade Uranus felt too soft and Jupiter too hard. Stuor tolerate wider rubber hardness variations.
2. Stuor blade is 1-2 mm shorter in length and 0-1 mm wider. It is much less height heavy. Stuor felt much lighter and much more maneuverable at fast reflex arm and wrist movements.
3. 301z is better in service. Faster, sharper over the net and more spin. Stuor needs more wrist work to create same service quality.
4. 301z is a bit more spiny in short game. Stuor can drop shot better. Stuor is safer in service receive because it returns shorter.
5. Stuor is much safer in intermediate medium power rallies. Stuor FH is spinnier with my limited technique. Stuor FH has higher throw.
6. 301z has more BH power with enough control. 301z needs better FH technique to discover full power potential then average 1800 player has.
7. Stuor has better BH block especially out of position. It can block shorter and with excellent above net height precision.
8. 301z has infamous composite click sounds when composite comes into scene. Comparing to 301z the Stur (FH) ALC acts earlier but more mildly. Stuor's BH felt almost pure wood and composite works for more speed and bigger sweet spot then for artificial feel.
9. I prefer straight handle. Stuor have comfortable handle thickness. Stuor unlike many blades I have used does not need sanding racket neck wings. I will try very thin handle overgrip because the handle is a bit raw in touch.
As general rule: harder blades have crisper feel but are more difficult to use effectively. Thin top ply wood hardness is not the main factor towards overall blade hardness.
It will be interesting to compare directly to Stiga Clipper Wood but it will not happen soon unless I would fatally damage a new Stuor blade.
