What is the distinction between Assets and Supplies, particularly when it comes to smaller durable goods such as hand tools or shredders?

I have many durable items that I've purchased for my sole proprietor business. Are there criteria for which must be declared as assets? I prefer to list them as supplies so I don't have to track depreciation costs. Here are a few examples:

  • Laptop: $2000
  • Workbench: $200
  • Paper Shredder: $65
  • Measuring Tape: $10
