So many things are made these days to be disposable: And that's fine for disposable plastic razors and cartridges, or some of the cheaper rechargable and battery powered mens hair trimmers. They have their place in a mans hair-grooming arsenal. For those of us who've learned the value of buying quality in the first place - and caring for our tools - know the value of buying Pro grade clippers that barbers and salons do. In particular Oster and Wahl trimmers can last a decade or more with proper care - and replacement blades are readily available to get them cutting 'like new' again for a fraction of the cost.

In general these companies have stayed true to their blade designs and manufacturing - without needlessly changing them every year. So it's easy to find replacement hair clipper blades or as important - replacement hair trimmer guides - today - for that trimmer you bought years ago.

FYI: If you own or buy one of Wahls clippers - you may find their Wahl METAL CLIP attachment comb sets to be vastily superior to the standard plastic guides. The spring metal side clips are far more snug to eliminate the guide popping off from excessive pressure or normal wear and tear that cheap plastic combs are prone to.
