Also known as Obeche, Wawa, Arere, Ayus, M'bado, Bado, African Maple, Eguess, Xwetin. Soft, tends to tear easily in thinner plys. Mainly an outermost ply wood, pairs up well with many woods. It is a lightweight, flexible wood that is excellent for close-to-the-table counterdrive play. Ayous is useful to maintain some lightness in the core of the blade but not be as crazily light as balsa. - Specific gravity = 0.38 g/cm³ - Monnin Hardness = 1.1 - Crushing strength = 30 MPa - Bending strength = 52 MPa - Modulus of elasticity = 7260 MPa - Janka = 430 lbf (1915 N) Balsa Binomial name: Ochroma pyramidale Also known as Balso, Pau de Balsa, Lanu, Lanilla, Guano, Gatillo, Topa, Algodon, Bois Flot. An extremely light, soft, porous, springy wood that has a non-linear effect at ball contact; hard, direct contact results in a big springing effect, while light or grazing contact results in a more controlled carom, and the difference is greater than what you'd expect. Readily available but not usually in widths required for blades, so gluing will most likely be require. Primarily useful as core and in rare cases second plys due to its fragility; deteriorates very quickly unless sealed. A thick balsa core tends to result in very springy, offensive blades. Due to its softness, it can allow the ball to sink in, resulting in high dwell time, which is good for loopers and choppers who want to manufacture a lot of spin. Also, due to its softness and non-linear effect, it is useful for deception and spin variation. - Specific gravity = 0.14 g/cm³ - Monnin Hardness = 0.3 - Crushing strength = 11 MPa - Bending strength = 20 MPa - Modulus of elasticity = 3710 MPa - Janka = 90 lbf (400 N) Basswood Binomial name: Tilia americana Common Names: Basswood, American Basswood, Lime, Linden.

The genus is generally called lime or linden in Britain and basswood, linden or lime in North America. Also known as Bee-tree. A harder wood, but still used in lower end all-round blades. Basswood has been a mainstay in racket making for over fifty years due to its high degree of control and economical price. It is favored by the close-to-the-table counterdriver as well as players looking to purchase their first professional racket.

'Kiso' denotes the top Hinoki woods, available only from a single location in Japan. Considered the 'golden' wood of blades, Hinoki is a form of Cypress, and much of the Hinoki used just as outer plies is really Cypress. Hinoki has the property of being very soft with a nice soft touch in the short game, but very fast when hitting. The biggest drawbacks are probably weight and cost. Kiso Hinoki is used for blade manufacturing only when having 300 years or more in age. It can be found in all types of veneers in table tennis blades. - Specific gravity = 0.43 g/cm³ - Janka = 300 to 800 lbf (depending on the species of cypress) Kiri Binomial name: Paulownia tomentosa Also known as Paulownia, Royal Paulownia, Princess Tree, Empress Tree. Kiri is the Japanese name for Paulownia. A light weight, soft but torsionally stiff type of wood, mainly used as core veneer. (Almost every Butterfly table tennis blade that is made in Japan has a Kiri core.) More durable, heavier and harder than Balsa. (This is one of the main reasons why Butterfly blades are heavier than other manufacturer's blades.) - Specific gravity = 0.26 to 0.35 g/cm³ - Crushing strength = 21 MPa - Bending strength = 38 MPa - Modulus of elasticity = 4380 MPa - Janka = 300 lbf (1335 N) Koto Binomial name: Pterygota macrocarpa Also known as Anatolia, Poroposo, Ofete, Kakende, Ikame, Ake, Awari, Kyere, Kefe. Soft topspin wood, typically used in extremely thin outer plies to produce a faster and stiffer blade. Great wood for players who rely on both looping and countering techniques. Koto wood surface plies encourage crisp, fast blocks and hard hitting for sharper ball contact and faster rebound. Usually quartersawn for the pattern. - Specific gravity = 0.59 g/cm³ - Monnin Hardness = 2.5 - Crushing strength = 54 MPa - Bending strength = 105 MPa - Modulus of elasticity = 12080 MPa - Janka = 940 lbf (4185 N) Kukui Hawaiian wood.   Larch Binomial name: Larix decidua Common names: Meleze, European Larch, Common Larch, Alerce, Larice.

Common names: Edjin, Edzil, Muizi, Edzui, Yaya, Bokanga, White Wenge. - Specific gravity = 0.82 g/cm³ - Monnin Hardness = 5.8 - Crushing strength = 73 MPa - Bending strength = 128 MPa - Modulus of elasticity = 16830 MPa Limba Binomial name: Terminalia superba Also known as Korina, Ofram, Frake, Afara, Akom. A West African wood, Limba is the classic European topspin wood (as compared to Hinoki, which is the classic Asian topspin wood). Heavy and fast, but not springy, Limba wood adds the soft feel and great control needed by today's modern topspin players. It is lighter and softer than Hinoki or Koto. Limba wood changes its color as the time passes so it is sometimes hard to spot a Limba wood by its color. Although Limba wood is soft, it can't give a soft feeling to the blade by itself, and when used with other veneers, a Limba blade can give a hard feeling. Limba has excellent acoustic properties and provides a good acoustic click sound when used with speed glue effect rubbers. Its vibrations or flex is liked by topspin players. The higher the thickness of the Limba ply, the greater the blade's hitting ability. - Specific gravity = 0.45 to 0.65 g/cm³ - Monnin Hardness = 2.4 - Crushing strength = 47 MPa - Bending strength = 86 MPa - Modulus of elasticity = 10490 MPa - Janka = 670 lbf (2980 N) Mahogany Binomial name: Swietenia mahagoni Mahogany. - Specific gravity = 0.57 g/cm³ - Monnin Hardness = 2.5 - Crushing strength = 46 MPa - Bending strength = 77 MPa - Modulus of elasticity = 11820 MPa - Janka = 1070 lbf (4760 N) Mansonia Binomial name: Mansonia altissima - Specific gravity = 0.66 g/cm³ - Monnin Hardness = 3.8 - Crushing strength = 60 MPa - Bending strength = 110 MPa - Modulus of elasticity = 13620 MPa - Janka = 1390 lbf (6160 N) Meranti Binomial name: Shorea spp. The five main groupings for Meranti (Lauan) are: - Dark Red Meranti - Light Red Meranti (Shorea leprosula) - White Meranti (Shorea bracteolata) - Yellow Meranti (Shorea maxima) - Balau.

In France, Common Spruce is often falsely called "Sapin" (Abies alba) and "Sapin blanc du Nord" is used to speak of Common Spruce coming from Scandinavia or from Eastern Europe. Called Fichte in Germany. Used to create better speed, Spruce plies result in big sound and good feeling when you hit the ball, but when this ply comes too much close to the rubber, the sound and feeling are too powerful, and the ball will not be very spinny, so it is better used beneath a surface ply.
