I made a custom tool based on a "reverse action" stainless steel tweezer. ★ Materials: Reverse action stainless steel tweezers, stainless steel (bolts, nuts, washers) ★ Operation: ① Pinch the tweezers with your fingers to open the tips. ② Place a micro-needle between the open tips, and release your fingers to close the tips. ＊This allows for fine positional adjustments. ③ Hold the nut with your fingers and tighten the bolt with the included 2.5mm hex wrench. ＊This securely fixes the needle. ＊If using a wrench to hold the nut, it will be 5.5mm. ＊Both tightening and loosening can be done sufficiently with your fingers. ★ Size: Length 90mm, Width 9mm (approximate values) ★ Other: Includes a plastic case and a 2.5mm hex wrench. ＊The needle in the photo is not included. #NeedleSharpening #NeedleMaking #TanagoNeedleVice
