Mcusta makes some beautiful Damascus blade folders.
Mcusta
Small folders
Truly high quality at a great price point. Manufacturered in Seki, Japan
The smaller folders can be had for approx. $115 on the online knife shops and Ebay.
I have 2 of their 33 layer Nickel Damascus steel w/V10 stainless steel core folders for many years. One small and one large.
The edge holding is fantastic. Better than any other folder I have.
You really won't find any Damascus folders of quality for $50.
Boker makes some high quality Damascus folders that cost hundreds of dollars.
The model you listed is made by a division of Boker, manufacturered in China, and as was mentioned, is not that great of quality.
Below are the MC-52D w/2.75" blade and the MC-114D w/3.25" blade
