Did some training with my Lishi and the effects of metal fatigue took their toll and the tip broke off but I wasn't upset. In fact, breaking my Lishi has taught me lots of new things about Locksport. Below is a list of everything I learnt from breaking my Lishi.
1. Lishi tools and heavy tension don't mix. Light tension is your friend when picking with a Lishi.
2. It's normal for pins to drop after you've set them.
3. If something is stuck, don't force it. This is what damaged my Lishi.
4. Take your time. There's no rush to get your lock open.
5. Practice makes perfect. Keep trying and you'll eventually get your lock open.
