Electric chainsaw and jigsaw: how to choose for gardening and DIY.
The two searches often appear "together" on Google because they solve different but common problems in homes and small businesses: the electric chainsaw (for pruning and cutting firewood) and the jigsaw/vertical saw (for curved cuts and trimming in wood, plastic, and even metal).
The right purchase depends less on the "most expensive model" and more on choosing the right type of tool, blade/chain, and safety features for the job.
In this guide, you will find a simple method for making decisions, with checklists, common mistakes, and a final section for internal linking on the UMBOX blog.
1) Electric chainsaw: when is it worth it (cable vs. battery)
Electric chainsaw with cord (230V)
It is the typical choice for:
-
Regular trimming at home (firewood, branches already on the ground, maintenance)
-
when there is a power outlet nearby and the workspace is controlled
-
For those who want simple maintenance (without fuel)
Weak point: the cable limits mobility and requires working with an extension cord and more attention to positioning.
Battery-powered chainsaw
Good for:
-
Pruning and garden maintenance with freedom of movement.
-
For those who value low noise levels and comfort in residential areas (very relevant in Portugal).
-
who already uses a battery platform for other tools
A guide from Husqvarna Portugal focuses precisely on the importance of choosing the right model according to its use (garden, farm, pruning, firewood), reinforcing that battery-powered options can offer a balance between performance and comfort.
2) How to choose a chainsaw: 6 "buyer" criteria (what Google wants to answer)
2.1 Power and work size
If you're going to cut harder wood or larger logs, you need a more capable chainsaw. Husqvarna explains that for larger trees and hardwood, you should choose a larger, more powerful chainsaw; a model that is too small is subject to unnecessary strain and wear.
Rule of thumb:
-
branches and light firewood → entry/media range arrives
-
Larger trunks and frequent use → move up a level (or consider a more robust alternative)
2.2 Guide (blade) length and “what you will actually cut”
A longer guide bar provides reach and capability on larger logs, but increases weight and can reduce control. For home use, many people buy "extra" and then avoid using it.
The right question: what is the typical maximum diameter of the logs/branches you are going to cut?
2.3 Safety: chain brake and reverse protection
The chain brake is a key element. Husqvarna describes safety requirements as kickback protection and a chain brake to stop the chain in case of kickback/improper handling.
There are also practical descriptions of how the brake can be activated manually and/or by inertia.
Important note: “Kickback” is one of the main risks — if you lack experience, avoid felling work and focus on controlled pruning/firewood.
2.4 Correct voltage of the current (greatly underestimated)
An improperly tensioned chain is a risk and reduces performance. STIHL always recommends checking the tension before using the chainsaw and warns that excessive tension increases stress on components and can cause damage.
A technical guide in Portugal describes a simple method: the chain is correctly tensioned when, upon lifting it in the middle of the blade, you can see the base of the guide links.
2.5 Chain oil and basic maintenance
Chainsaws require proper chain/guide lubrication. Regular maintenance is not optional — it increases safety and service life.
2.6 PPE: the minimum kit for working with confidence
STIHL recommends the use of the PPE indicated in the manual, including (depending on use) boots and trousers with cut protection, gloves, goggles, hearing protection and a helmet.
And there are specific pages dedicated to PPE for chainsaws and gardening/forestry work.
You can also find institutional references in Portugal with lists of personal protective equipment (helmet/visor, ear protectors, gloves, leg protection and boots).
3) Jigsaw (vertical saw): how to choose one for clean and fast cuts
The jigsaw is one of the most versatile tools for:
-
curved cuts, cutouts and "shapes"
-
Straight cuts in wood (with guide and technique)
-
Works on plastic and metal (with the correct blade)
3.1 What to compare in a jigsaw (without marketing)
A technical article in Portuguese indicates typical factors in the selection: power, suitability for the material, and machine characteristics.
In practice, the criteria that most impact the purchase are:
-
Variable speed (strokes/min) : more control for fine cuts and different materials.
-
Pendulum (orbital) action : accelerates cuts in wood, but may reduce finish.
-
Cutting depth (wood/metal)
-
Quick blade change
-
Ergonomics and vibration (especially during prolonged use)
Bosch, for example, highlights in the PST 900 PEL the pendulum function for quick or precise cuts, the selection of the number of strokes and the SDS system for quick blade change with one hand, in addition to a cutting depth of up to 90 mm (depending on the material).
3.2 Pendulum action: when to use (and when to turn off)
-
Linked (levels 1–3/4) : wood, fast cuts, less finishing required.
-
Off (0) : tight curves, laminates, cleaner cuts, metal
That's precisely why many technical specifications "sell" the pendulum motion as an advantage—it speeds up the work.
3.3 The blade represents 50% of the result (and this is where you gain SEO + sales)
For a tico-tico (a type of small, sharp object used for cutting), the rule is simple: the wrong blade ruins the cut , burns wood, and warps metal.
A guide on razor blades explains that the choice depends on the material (wood, metal, plastic), and that the size/shape of the teeth and the spacing are crucial.
There is also Portuguese (Brazil) content focused on choosing the right blade for wood and the type of cut (straight/curved/angled).
Quick blade checklist
-
Fast wood (larger teeth)
-
wood finish/laminates (fine teeth)
-
metal (fine teeth, appropriate blade)
-
curves (narrower blade)
3.4 Bevel cuts (angles) and adjustable base
Many jigsaws allow you to adjust the base for bevel cuts (e.g., up to 45°), something frequently mentioned in manuals and product data sheets.
4) Which tool to buy first: quick decision (real-world cases)

FAQ
What is the safest thing about an electric chainsaw?
Chain locks and kickback protection are essential; there are safety requirements that include brakes, locks, and kickback protection.
How do I know if the chain is properly tensioned?
A technical reference indicates that, when lifting the chain in the middle of the blade, it should be possible to see the base of the guide links; and STIHL always recommends checking the tension before use.
Jigsaw is good for metal?
Yes, with the correct blade for the metal and the appropriate speed; the choice of blade depends on the material and the type of teeth/spacing.
What is the pendular (orbital) function in a tico-tico (a type of flying bird)?
It's a movement that speeds up cutting (especially in wood). Bosch describes the pendulum function as a way to achieve fast or precise cuts, depending on the setting.
