Hi Friends,
I hear you all. I think this is a case where all points of view are right. At least they are for me. Although, as a former subsistence farmer, current school teacher and striving father of two, I tend to err on the cheap side. Primarily, because I never have a sizable lump of cash at one time.
For probably not much more than the price of a fully outfitted professional knife grinder I have outfitted (over several years) my shop with: 2 bench-top drill presses, a couple of bench grinders, a Baldor driven jeweler's buffer, a step/belt driven Coote grinder, an O/A torch, a Lincoln AC/DC buzz box, an HF cutoff grinder, two 4.5" angle grinders, a Sawzall clone, a jig saw, a horizontal/vertical band saw, a Griz knife grinder/polisher, a Griz dust collector, an old Craftsman 30 gallon air compressor, a sandblast cabinet (floor model), a solid fuel forge and a forced air gas one, a jeweler's burnout oven, vacuum chamber and gravity assisted caster, centrifugal caster, two flexible shaft rotary machines, a 6x48 belt and 12" disc sander, a 12" Craftsman band saw, a 10" table saw, a Makita chop/miter saw, a 12" Ryobi planer, various palm/belt sanders and a electric hand planer and numerous wood-, metal-, leather-working and mechanic hand tools.
Sure I've had some equipment failure, but sometimes I able to render repairs. If not, oh well, it was cheap, so's another!
Thanks be to friends and family, yard sales, Craig's List and eBay (for upgrade selling too), trading, even curbside trash and dumpsters.
I have found that top of the line consumables are usually the wisest purchase, but even then sometimes not. For instance, I definitely don't buy my chemicals the same place our chemistry science teacher does. A gallon of dry acid pickling compound, aka sodium bi-sulfate, (PH balancer) from a pool supply house can be bought for less than the cost of a few ounces from a laboratory or jewelry supplier.
On-the-other hand, buying the best materials is a definite objective. If truth be told, I've spent way too much of what we can't afford in this realm. I console (cajole?) myself that it's an investment, as the material should appreciate over time. I even fantasize about turning it into stunning knives of superior value at some point in time. Of course, this will only work if I can invest personal time in my shop to further my skill sets too. That's the investment/cost that is the most challenging for me....time!
All the best, Phil
