This is just going to be some easy text regarding the ribbed Alox scales you find on the 93mm Pioneer Range. From 1957 until today you find the checkered scales
with several colors in history. You find different emblem designs and tang stamps as you know. It could be some different names used on the pattern on the Alox knives. On the pictures you see some 93mm models with checkered scales. I personally call them ribbed
and if you take a look on the Victorinox information you see that they also call it ribbed. Anyhow expect on the internet that you find different names for this with checkered as one name.
Victorinox call the Alox scales to be punched from aluminum and embossed with a ribbed pattern. This you find on their website on the limited Alox models with such a pattern. The pioneer Range 93mm scales from
1957 until today got a few different small design modifications. In general the scales are very similar from the beginning. The older Cadet 84mm had a different design with ribbed lines.
The modern Alox models are anodized a bit better and you can find recycled aluminum used for example. The 93mm category is phenomenal and as you know you will find different dividers used in history as well.
