While ball-milling at room temperature is a popular technique for preparing hydrogen storage materials, the use of this method frequently resulted in hydrogen losses during milling. Cryogenic ball milling (or cryomilling) is a relatively poorly explored preparation technique suitable for producing temperature-sensitive materials.

Speaking of milling, the one aesthetic extravagance this time around is the milling of the back edge of the putter. All three of the blade models have the back edge milled to match the pattern on the face. The BB46 misses out on this milling as well as the Bettinardi name on the neck. The final take is that these are great looking putters.
