Giant Lifting's kettlebells are die gravity casted which means molten iron is poured from above into our metal molds. Some manufacturers use sand casting which means the kettlebells can have rougher surfaces, less accuracy with the weight, and lower overall strength.
We don't add any fillers to cheapen the product which potentially leads to cracking in the future. Once the mold is poured and dried there are excess edges that require the manufacturer to grind down to create a smooth finish around the handles and base of the kettlebell.
This allows for a smoother handle and a flat base required for varying exercises. There are easy color coating markers along the handles to find your desired weight.
