Applicable Scenarios
Trial orders for startups, standard blade procurement, budget-sensitive small and medium-sized enterprises, price-sensitive and risk-controllable orders.

Prioritization
Long-term stable demand - choose manufacturer (cost-optimal).
Multi-species technology dependence - choose head distributor
Urgent and sporadic purchases - local retailer or platform flagship store (balancing timeliness and fidelity)

Risk control
Online store purchases need to verify the authorization qualification, and give priority to the brand's own store.
Assess the technical team background of the reseller (e.g. whether there are certified engineers).
Regardless of the channel, it is necessary to verify the material of the tool (such as tungsten steel blades need to be accompanied by an elemental analysis report), check the packaging anti-counterfeiting mark, to avoid buying recycled refurbished blades.
