Using a USB Cleaver on property you do not own is a felony under the Computer Fraud and Abuse Act (CFAA) in the US, Section 3 of the Computer Misuse Act in the UK, and similar cyber-sabotage laws globally. Destroying a $500 motherboard is an act of vandalism; destroying a hospital’s patient data server during a ransomware attack by using a cleaver on the backup server is an act of terrorism.
