The most common test for testing wood hardness is known as the Janka hardness test. The actual number listed in the wood profile is the amount of pounds-force (lb f ) or newtons (N) required to imbed a .444″ (11.28 mm) diameter steel ball into the wood to half the ball’s diameter. While most people would be looking for the hardest wood, just out of curiosity, here’s a list of the ten softest woods on the site. Keep in mind that five out of these ten woods (including the three softest) are considered hardwoods. This just goes to show that the terms hardwood and softwood merely refer to the botanical classification of the trees as either conifers (softwoods) or angiosperms (hardwoods). There’s no guarantee that any given hardwood will actually be hard! Note: A hardwood named Quipo (Cavanillesia platanifolia) is commonly reported as the softest known wood, with an alleged Janka hardness of 22 lb f (98 N). However, the wood is omitted from this list for two main reasons. First, it is virtually unobtainable and not commercially available outside of its natural range in Central/South America. Secondly, the purported hardness seems highly questionable, especially in light of the fact that Quipo seems to be very susceptible to rot, and on one USDA test, it was remarked that “the results for quipo may have been influenced by the presence of considerable decay.” Furthermore, when comparing Quipo with Balsa, it has been shown that the two woods are virtually identical in hardness, with the absolute lowest recorded Janka hardness values, in the range of 20-35 lbf (89-156 N), were actually from Balsa, and not Quipo.

Can you cut basswood by hand?

Very thin basswood can be cut with an x-acto knife, though it is difficult. But if the basswood is thick enough that you can't easily flex it, you'll need power tools. A table saw or circular saw would probably be best, if you're making straight cuts.

Up to 1/8" Basswood can be treated the same way you'd cut 3/16" or 1/4" Balsa. Instesd of a #11 in a #1 knive handle, you go up to a #2 or #5 Handle with a SHARPENED and STROPPED #2 or #24 blade. Some folks use single edge razor blades on the thicker stuff or scaples have also proven to work very well on thick tough materials.Orporg if your having trouble cutting Basswood your going to hate Lite Plywood, where your fighting cross grain cutting regardless of the direction of your cuts as well as at least two layer of dried waterproof glue. It can still be done with a blade but your gonna have to bulk up a bit firstAs with any woodworking tool, to work well your knifes Must be sharp to work properly and with the least amount of worker fatigueLet the knife blade do the work, apply firm but not too much down pressure on the blade as you draw it along your straight edge. This is very ture on all Cross Grain cuts. Make a series of passes instead of trying to muscle your way thru with a single pass or two.With a little practice you'll be making nice clean straight cuts even on the cross grain passesMy Scroll saw, band saw and razor saws are reserved for Heavy materials, 1/4" and thicker, plastics and metals. for Model and LMR's fins and such you not need no stinkin sawsHope this helps.
