1. **Initial Cost:** The upfront cost of purchasing 100 high-quality blades can be relatively high compared to cheaper, lower-quality alternatives. This may be a barrier for casual users or those on a tight budget.

2. **Potential for Overkill:** If the user does not frequently require a wide variety of blade types or sizes, purchasing a set of 100 blades may be unnecessary. This could lead to unused blades taking up storage space.

3. **Maintenance Requirements:** While SK5 steel is durable, it can still rust or dull over time if not properly maintained. Users will need to clean and dry the blades thoroughly after use and occasionally apply a light coat of oil to prevent corrosion.

4. **Safety Risks:** Sharp blades pose a risk of injury if not handled carefully. Users, especially those new to working with utility knives, may need to take extra precautions to avoid accidents.

5. **Limited Specialization:** While the set is versatile, it may not include specialized blades for highly niche applications. Users with very specific needs might still need to purchase additional blades separately.

6. **Environmental Impact:** The production and disposal of metal blades contribute to environmental concerns. Users who prioritize sustainability might prefer reusable or recyclable alternatives.

7. **Potential for Overwhelming Choice:** With 100 blades to choose from, users might feel overwhelmed when selecting the right blade for a particular task, especially if they are unfamiliar with the different shapes and sizes.
