S-line Blades

Designed with spearfishing in mind these premium carbon fins take performance and efficiency to a whole new level. Designed for hard kicks where the blade is put under extreme force. They are slightly shorter than the V3 blades that have been a mainstay on the market for years. Alchemy is the name in carbon blades that has stood the test of time. Made from Pre-pregnated carbon layers the quality and craftsmanship is great and the price is excellent.




S FOR SPEARFISHING

Ground-breaking new fins that are progressive in every way. With top notch performance and configurability, they are designed to enable a wide range of spearos push the boundaries of what is possible. Every aspect of the Alchemy S is designed in pursuit of greatness. Based on a completely new blueprint which aims to help spearos outperform themselves even in the most extreme scenarios, they are engineered to go full force, all the time. From there anything is possible. S for Speed, S for Safety, S for Spearfishing.

MEET THE S

Our S model is the latest addition to the Alchemy family. Tailor made for spearfishing, it packs everything, in terms of performance & efficiency, into an advanced specialty. The new length (-3cm compared to V3) makes the blades a lot faster & easy to manoeuvre under any circumstances and the reinforced base of the blades offers maximum results for all diving styles. Following the V3 model, their shape fits Pathos footpockets with an angle of 23 degrees. We kept the extraordinary mirror finish on the blades' front side and matte finish on the back. Serial number tag is now embedded into the blade's lamination ensuring the authenticity of your genuine alchemy product along with a hologram tamper-proof individually numbered tag on your warranty certificate document.

NEW COLOR COMBINATIONS

Having the first worldwide innovative design of coloured silicone water-rails, we decided to offer more. Alchemy S blades come with an extra unique colour, never seen before in the alchemy pallete; Tuna Blue Metallic. The previous colour variations, are also available. In other words, we offer all it takes for you to be in constant love with your equipment.

CONSTRUCTION

Alchemy S Carbon Fiber Blades offer a new revolutionary design with 11 (eleven) Carbon Fiber layers for ultimate energy transferring and top performance. They are manufactured in compliance with the most demanding and modern standards in constant ambient temperature and humidity. 40 tons of total pressure combined with vacuum assistance (VRTM) and 12 hours post curing in temperatures controlled through PLC (Programmable Logic Controller) with a deviation of less than ± 0,1°C.

BLADE ENDING SHAPE

Alchemy S Carbon Fiber blades are manufactured ending in a dolphin tail shape (D.Tail). This shape gives the best results based on hydrodynamics studies (Rensselaer Polytechnic Institute / T. Wei) and tests made in C.F.D. software (Computational Fluid Dynamics). The dolphin tail shaped ending gives the maximum thrust with the least possible energy consumption.

WATER RAILS

In each alchemy S Carbon Fiber blade, there are specially designed water rails made of 100% silicone. The design was made in a three-dimensional (3D) CAD environment and produced in United Kingdom by a high end silicone production facility. Trials and studies in C.F.D. software showed that this water rail detains and drives the water on the blade without losing its shape even in the toughest conditions. The fact that even in the limit bend of the blade, the water rail retains its shape, drives the water from the beginning of the stroke and provides immediate response to the diver's moves. Alchemy water rails offer hydrodynamic design and the absolute superiority of silicone to common rubber on strength, original shape maintenance and strength under extreme conditions.
