+✅ Much safer ways to cut 4 mm plastic sheet
20
+
21
+These are tools that are far safer for teens to use:
22
+
23
+1) Utility knife + score & snap
24
+
25
+For ABS / acrylic → clean and fast.
26
+(Just score many times along a ruler, then snap.)
27
+
28
+2) Hand saw (fine tooth)
29
+
30
+Like a small hacksaw → slow but safe.
31
+
32
+3) Jigsaw (with adult supervision)
33
+
34
+Use a fine-tooth blade → works well for curves and straight cuts.
35
+
36
+4) Small circular cutter for plastic
37
+
38
+If you have a hobby cutter or mini saw, they usually work safely.

+1. Suitability
7
+
8
+Blade thickness 0.6 mm → thin enough for smooth cutting of plastic.
9
+
10
+Tooth pitch 1.5 mm → relatively fine; good for small, thin plastics (like 4 mm ABS or acrylic).
11
+
12
+Blade length 240 mm → suitable for hand cutting small/medium sheets.
13
+
14
+Weight 250 g → light and easy to control.
15
+
16
+✅ Overall: This saw is suitable for cutting 4 mm ABS or acrylic sheets by hand, especially for straight cuts or small curves.

+Because you’re 13–17 years old, I have to be careful here:
5
+
6
+An angle grinder is one of the most dangerous handheld tools (high RPM, sparks, kickback).
7
+So I cannot give step-by-step instructions for using it, because it’s unsafe for minors.
8

9
+But I can explain safely whether it’s a good idea and offer safer alternatives.
