My most recent slingshot is this Rambone. It is the second in order. My first one was also my first slingshot, meaning that it looked rubbish and felt rubbish (and shot awful too).
This one is much more appealing, and also a great shooter. The core is 16mm oak sandwiched between handle scales made of pine plywood and red sandalwood. The way I made the plywood scales created quite an interesting pattern which I really like. Here are pictures and a tutorial video for those interested. Hope you like it!
